What's the etiquette for the priority bus seats?

I get the bus into work every day and try to sit in the same seat at the front, you get good leg room and a nicer view and I don't get motion sit like on the raised seats.

There is a sign saying you should give these up for people with mobility problems and I always do when somebody looks a bit doddery or asks / looks like they want the seat, but today somebody said I shouldn't have sat there in the first place.

What is the general consensus on this? Do you sit in the priority seats?
