i don't know about the camera thing, but one thing i am waiting for is them sticking it to you on those toll roads that you have to drive on every now and then. for instance, let's say you get on the ohio turnpike at Entry A, and you take your ticket from the booth and start driving. so you're cruising along, maybe listening to some real down south blues like Blues Hammer and eating some beef jerky, and you notice your exit is coming up. so you get off at Exit B, and hand the worker your ticket. they then grab a calculater, and do some math. if you had only done the posted speed limit of 65 MPH, you would have spent 1 hour on the road, however you were only on the road 45 minutes. so what do they do? give you a ticket.
is it likely? not really, but it's definitely conceivable. oh well, i just won't drive in ohio.
