Speed barcodes on roads

 The car reads large barcodes painted on the road surface and indicates the speed limit on the speedometer.

GPS-based speed governor for cars http://www.guardian...3604,425344,00.html
Similar idea in the UK: GPS receiver controls car's maximum speed based on database of speed limits [wiml, Apr 19 2001, last modified Oct 04 2004]

       I saw this suggested on Beyond2000, which is sort of a corny title, nowadays. The idea was that your car would be self-ticketing, so that, if you went over a bar code too quickly and later got pulled over, your car would tattle on you. So, it's baked, at least in the sense that working prototypes did exist at one point.

       Spray-can artist cracks speed code! Freeways reduced to 3 mph crawl! In-city speed limits through the roof! Chaos reigns!

       I don't want a computer telling me what I can do---unless the road is totally designed, built, and maintained by a computer

       Baked, after a fashion. On the Nullarbor (no tree) Plain in Oz the police have marked white lines across the road.   

       They spot you from a light plane and time you from one mark to the next. If you're too quick they buzz you to ID your car, then radio ahead to the nearest police station to pull you up and ticket you.   

       The temptation to speed is pretty strong. There's a straight stretch (no bends at all) of about 195km at one point (see link)

       Police use the same technique here in the US too. The adventurous soul might paint extra lines on the road to confuse the skyborne.

       Think of the fun of spray can enhanced speed limits. Why not instead make the car CONFESS to your speeding by printing out a long roadtop barcode with your driver's licence number and a humbling apology? Traffic endangerment zones would be visibly obvious by the clutter of barcoded doodling.
