GM, BMW Working on Cars That Know the Speed Limit

GM’s European unit Opel and BMW are working on cars that can recognize speed limits on any road and inform the driver.

Although this technology makes me vaguely think of my dad riding shotgun while I worked through my learner’s permit, it could be useful. No more speeding tickets when you drive into a new state and don’t notice it has lower speed limits.

The system is being tested in Europe where cars read traffic signs through digital signals and then display that information to the driver. The software still has some kinks, including problems reading digital signs, according to DriveOn’s Chris Woodyard.

GM says the system will eventually come to the U.S., but the sign recognition software will have to improve first. Until then, we’ll just have to rely on the patient voices of our fathers echoing in our heads — informing us that we're driving 2 mph over the posted speed limit.

Missed That Speed-Limit Sign? Your GM Car Could See It for You (DriveOn)



Good idea, but I worry about the implications for electronic nanny systems in our cars.


It will be defeatable I'm sure.

Several navigation systems already know speed limits. They don't do anything about it though.


This system is already working in Europe on the new e-class from Mercedes. And because I tried it, I can ell you it works very good. The concern in North-America is the fact that signs are very differents from one province (or one state) to the other.


Wait till your car can ticket you...


+1 Brady Holt!

My little Garmin Nuvi does that for me already.

This crap does not allow any "plausible deniability."


btw, I really have read in a magazine somewhere that you're never supposed to admit that you knew the speed limit and that you knew you were breaking the law. as in:

Officer: "Do you know how fast you were going?"

You: "No officer, I did not."


another thought:

if the car's display reads (by mistake of the sensor) "Speed Limit 100," can you say that you were mislead and made an honest mistake? After all, in civil courts it's about "more likely than not." hehe

Wow, that is a really great idea!
