Using Bluetooth to show off car at car show?

Bluejacking in 2026? Everything old is new again.

[-]

devin122@reddit

There is no way to do this nor should there be. Can you imagine how annoying it would be if every time you walk past a business they trigger a notification on your phone?

[-]

Not only is this already a thing, it was so overused that now iOS and Android changed the Bluetooth behaviour to make your phone only be discoverable when you're on the Bluetooth menu for this exact reason.

Holy chit. That tripped me out so hard. I'm scared now. This hit way to close to home.

[-]

7HawksAnd@reddit

It’s a pretty solid existential warning of something that already exists today, though without the pizzaz, presented as satire with whiz bang.

[-]

windraver@reddit

Oh damn I remember when this first came out. We thought it was funny back then but now it actually might happen

[-]

arttechadventure@reddit

Ugh. That was horrifying and disgusting and definitely what is in the not so distant future.

[-]

Threedawg@reddit

That was horrifying

JerDawg410-BL4NK@reddit

This deadass happens in some places when i was in Indonesia, either it was just coincidence everytime or they somehow knew

[-]

pm-me-racecars@reddit

I like to air drop memes to everyone on my airplane flight.

[-]

mr_j_12@reddit

Best friends misses did it coming home from a music festival on a train. Combination of shock, laughter and confused reactions as people got airdropped grandma porn. 🤣

[-]

never_not_relevant@reddit

It has been talked about for years, I don't know if anyone still does it but Bluetooth beacons use to track you through malls/stores then use that information to send you specials.

Cops now track the IDs on tire pressure sensors to track people entering and leaving areas of interest.

[-]

lilsinister13@reddit

Cops hate indirect TPMS and cars from before 2007

[-]

Medical_boy_1295@reddit

It’s possible, very easily actually

[-]

tal125@reddit

No it isn't possible. Bluetooth wasn't designed to translate a push notification into a intractable hyperlink.

[-]

TwoThumbFist@reddit

How are some ways beyond airdrop that can be disabled?

[-]

AndrewIsntCool@reddit

I don't know nowadays but this was possible to do using a Jailbroken iOS 10 device, even sending pings to devices with AirDrop disabled (as long as the target device was on iOS ≤10.1)

Hasn't been possible for years though

I’d hate anyone’s car for the sole fact they’re air dropping some shit to my phone.

Use a QR code if you want to do something like this.

[-]

EEpromChip@reddit

Honestly this is the answer. Go to your instagram, there should be a way to generate a QR code from the page (Chrome / Firefox have extensions to generate QR from page) and 3D print it and stick it in your window.

[-]

therezin@reddit

Instagram even has a built-in thing for generating a QR code. Go to your own profile and there's a big button saying "share profile". That's the whole thing.

[-]

kjgjk@reddit

But even then nobody’s gonna scan it lol. Throw your instagram handle on your quarter window like all the teens do with their g35’s and be done

[-]

obi1kenobi1@reddit

This. I’ve often thought of making a QR code vinyl sticker that I could put on the windshield that people could scan to go to a website with more information about my car, but I’m super lazy and don’t want to have to make a website, and most of the time if someone wants to know more about the car they can just ask me because I’m right by it.

[-]

Whysoblunted@reddit

Absolutely no one wants some randoms build progress airdropped to their phone when he drives by lol

[-]

DislikedBench@reddit

LMAO right thats such a fucking hilariously stupid idea

[-]

Linetrash406@reddit

Op needs to research when U2 decided everyone would love the new U2 album automatically added to their phone. They hung them in gallows for it. Imagine what the reaction would be to a random fox body.

[-]

kjgjk@reddit

I remember hitting shuffle in my car on a first date and U2 played. Looked like a total goober thanks to U2 and apple

[-]

themigraineur@reddit

It wasn't even a good album

[-]

Linetrash406@reddit

In general. I’m not a U2 hater. Plenty of people like them. But that album sucked.

[-]

OldGrimMechanic@reddit

I called my Blue 1968 Roadrunner "Blue Devil" I won a lot of Drag Racing with that car. Did low 7's on the quarter mile.

[-]

Practical-Leave-3369@reddit

Fuck no.

[-]

Busterlimes@reddit

Attach ring doorbells all around your car.

[-]

Boilermakingdude@reddit

Pretty lame. Just put up a QR code. I don't want a bt ping.

[-]

showcarqr@reddit

We make free, QR code driven display pages for this. Like boomer boards for mobile phones.

[-]

poorboychevelle@reddit

Here I thought Boomer Boards were bad

[-]

ChikinCSGO@reddit

You could get an NFC tag that you stick to the car with a magnet, maybe make the magnet the Bluetooth symbol. People can tap their phones to open a link.

[-]

SirBrainsaw@reddit (OP)

This...i want people to have the choice of scanning rather than be forced upon the people.

[-]

obi1kenobi1@reddit

If you know someone with a Cricut have them cut a nice vinyl sticker of a QR code to put on the window. Lots of people don’t like them but they’d still likely be the most effective way for people to just quickly scan and get to a website compared to other methods. And maybe have the website written out underneath for those who just don’t trust scanning anything with their phone.

[-]

ChikinCSGO@reddit

Then this is the perfect option imo. Cheap, easy to setup, reliable and compatible. You could construct the site using lovable for an easy gallery if you aren’t familiar with websites. Or just have it link to your FB like you said before.

[-]

ILoveStealing@reddit

I think this is the best idea, but the RFID or tap-to-pay symbols would make more sense.

[-]

mr_j_12@reddit

I read it originally as you wanted to advertise your carshow, not your actual car. Fuck that, use a sticker advertising instagram/youtube handle/what ever on rear windscreen.

[-]

KdF-wagen@reddit

make a QR code

[-]

Zed32_Customs@reddit

Just make one of those boomer boards that tells everyone about your corvette

[-]

KdF-wagen@reddit

Make sure to include how it's ultra rare because its got the special shift knob that only came with an option code that you don't have.

[-]

Zed32_Customs@reddit

Gonna make that guy on youtube say "you need your timing advaaaanced"

[-]

KdF-wagen@reddit

lmao

[-]

WhippingShitties@reddit

Or just do what everyone does and put the insta handle as a sticker on the back or side window. Looks better than a QR and I don't scan QR codes unless I know exactly what it is, who is sending it, and why.

[-]

rohm418@reddit

don't scan QR codes unless I know exactly what it is

Same. We had a CISO at my company that drilled this into us.

[-]

WhippingShitties@reddit

I don't even scan for menus because it would be easy to plant a fake QR.

[-]

8N-QTTRO@reddit

This is a good way to get your tires slashed.

[-]

GeT_ReKt-A@reddit

If a car gave me adware I’d slash the tires

[-]

almost_red@reddit

You could use a flipper zero with the Bluetooth spammer. Wouldn’t link to anything though. Or just make an NFC they can tap to go there

[-]

whateverman33@reddit

Are some people just working on a car for clicks?

[-]

myfishprofile@reddit

Yes

[-]

whateverman33@reddit

Sad!

[-]

myfishprofile@reddit

Truly unfortunate imo, but at the end of the day it’s no different than the guy who stacks 6 blowers all chromed out on a car that travels less than 100 yards a year.

They are both doing it for attention

Not my cup of tea (I think its abhorrent personally) but not as far removed as you may first think

[-]

whateverman33@reddit

Good point, I was ignoring the old school small reach (car shows and neighborhood before social media) people and focusing on the click whores. I just want to drive a better car than I started with. But I also like beaters, nothing takes the smug smile off an AMG drivers face like beating them or giving them way too hard of a time with an old Mustang or twin turbo explorer lol

[-]

myfishprofile@reddit

Absolutely love my beaters, in my case I want to get a fast car the “cheapest” way possible….which was definitely not how things ended up

Which is how I ended up with my current monstrosity lol

[-]

whateverman33@reddit

Haha that’s great, neighbors probably love it on a Sunday morning too lol

[-]

sharkboy1006@reddit

i'm ashamed of the fact that we are the same species op

just print a qr code

[-]

aredd007@reddit

QR code sticker on the rear quarter windows.

[-]

Adjectif_@reddit

NFC tags…, you can read them with a phone, you need to be close to it tho, like when you tap to pay

[-]

wellwaffled@reddit

Think about what you’re asking. Do you really want EVERYONE to hate you?

[-]

FloridaMan_Inc@reddit

If I go to a car show and a car starts forcing push notifications to or opening website/apps on my phone, I'm keying it.

Fortunately, that's not how Bluetooth works and you can't just force a connection to someone's phone without their consent. As others have stated, a QR code is the closest thing you can get to this.

[-]

stevedrums@reddit

If you get a push notification you’re going to do property damage? That’s kinda fucked up.

Just revbomb and put your @ on the bumper like all the other clout chasers. Keep your digital herpes off my phone.

[-]

SirBrainsaw@reddit (OP)

Ok from what I've seen in the responses... it looks like a photo album under the hood would be best. I dont scan unknown QR codes. Thx all

[-]

RandyFunRuiner@reddit

You could make a sticker with a QR Code that says something like “follow my build” or “follow Bluetooth here” presuming that’s the name you’ve given to the car. As long as it’s clear the QR code is to a social media account or website for the car, I doubt that would turn away anyone who was genuinely interested.

Or just print stickers or a magnet with a social media handle for the car

[-]

devin122@reddit

I don't understand this. You don't scan unknown QR codes, but you would open a random link if it somehow showed up on your phone via Bluetooth notification?

[-]

spidey_bread@reddit

This might be the funniest post I've ever seen

[-]

Lee2026@reddit

Put an NFC tag on the car; you can place multiple, maybe even integrate them into stickers to explain where it’s taking you.

Then people simply tap their phone against the tag and can be directed to what you want

[-]

No,but you could use an RF sticker. With a nice design on it.

[-]

Bluetooth was a viking king from the 10th century.

[-]

SirBrainsaw@reddit (OP)

Trying for a unique approach

[-]

Komitsuhari@reddit

Your current approach would get your car pissed on, specifically the door handles

[-]

SirBrainsaw@reddit (OP)

Good thing they're lickable

[-]

Decipher@reddit

You misspelled awful.

[-]

Maxzillian@reddit

It's definitely novel, no doubt about it. However, being novel doesn't necessarily make it a good idea. This definitely falls into the realm of intrusive advertising and very few people will have a positive reception to that.

In the theme of what you're aiming for, I'm afraid I really don't have any great ideas. You could make your car an open bluetooth speaker, but that's also a pretty equally bad idea just from the perspective of being turned into a nuisance.

[-]

DoubleInvertz@reddit

Try a different one

Was using stickers like this on either rear quarter glass for a while (don't anymore because I remembered most social media is fairly evil 😅)

[-]

WillardFist@reddit

Remember when u2 put there album on everyone phone without permission and people were pissed? Don’t do that. If you’re doing something cool people will come by themselves.

[-]

Swolebrah@reddit

Make a boomer board and move on

You really like Bluetooth, huh

phalangepatella@reddit

Hey, just a heads up: it is their phone, not yours to annoy as they walk by your car.

Make little QR code placards and let the people walking around choose to find out more if they want.
