Isn't sign reading necessary for say, construction areas, that would have a lower speed limit? If so, researchers could do the same thing by placing false construction signs.
- gleenn 7y agoBut at least the software could assert that the construction speed was lower than what the map stated the speed limit was so you could only slow down a car which would hopefully be a safer failure.
- JMTQp8lwXL 7y agoCars slowing down when they shouldn't be can create dangerous situations, though I'd agree it's relatively safer when compared to speeding (particularly in residential areas, or roads not made for faster travel).
- rootusrootus 7y agoThis is actually one of my biggest gripes with autopilot. It's aggressive at following reduced speed limits, even when traffic is not. I don't know the solution, since the speed limit really does drop to 25-35 mph in a couple spots in our local freeway interchange, but traffic flows through at 55-65 mph all day long, and having the car suddenly brake to 30 mph is unexpected. If there's one thing you want to be on the road, it's predictable. It's when you deviate that accidents happen.
- rootusrootus 7y agoIt might be necessary for higher level self-driving, but AFAIK Tesla isn't doing that due to patent issues. Autopilot is just very fancy cruise control, and you're supposed to be in charge. You'd be expected to change the cruise control set point manually when you enter a construction area.
