Bosch develops Speed Limit Detector

My first speeding ticket was the result of a sudden speed limit change from 35 to 25 mph. I didn't see the sign because it was snowing, nor did I see the cop that was parked a few hundred down the road. If only I had Bosch's new Speed Limit Detector that uses a complementary metal oxide semiconductor (CMOS) camera placed below the rearview mirror to scan the road ahead and recognize speed limit and other traffic signs. The device can be programmed to give audible notification of the posted speed limit or simply a warning if you've exceeded the posted limit by a predetermined amount. The system is programmed to recognize traffic signs in both Europe and the U.S. and is equally effective in the daytime or at night, as well as in rain and snow. Where was this thing when I was 16?
