Guys, I've invented a device which will revolutionize the way we all drive. It's pretty technical, and it's still in the concept phase, but I believe it can be retrofitted into existing vehicle designs. Basically, it's a device that tells other drivers what you're about to do. It uses photons to project the intentions of one mind to another across space and time, at the speed of light. Like if you're about to make a turn, you'd be able to use this device to signal to other drivers what you're going to do, before it ever happens. You could probably use it to let others know you're about to change lanes too, I don't know. The potential seems unlimited. We'll no longer have to keep hitting each other because no one knows what we're about to do. Think of all the blood and aggravation it will save! I call it the "course teller", because it tells other people what course you're going to take. I see it catching on like wildfire and people will wonder how they ever got along without it.
