One possible mitigation could be the use of geocoded roadway metadata. I rented a car in France that had this - it would let me know when I was exceeding the speed limit based on my position. Not hyper-accurate, and so probably not a replacement for all road signs, but certainly good enough for many situations.
- smogcutter 9y agoWas thinking of this too, but what happens when the map and "ground truth" disagree? The machine would need to be able to identify the rare circumstances when it should trust the map over its senses. If it's capable of that, this wouldn't be a problem in the first place.
- SomeStupidPoint 9y agoWhen driving, that probably doesn't really matter: If the map and road sign disagree, just do what everyone around you is doing (ie, go with the flow) until you recover agreement. It's not perfect, but stretches out attacks to having to compromise long stretches of road and multiple vehicle types. If the cars for the next mile somewhere can find pace, the whole group can; similarly, if any kind of car can find pace, they can all use that to set. Obviously safety checks and such, but human drivers only loosely follow signs and often get behavioral cues from other cars -- why can't automated cars do the same when they get confused?
- dTal 9y agoI am now picturing a mile-long phalanx of self-driving cars gaily careening off the end of a destroyed bridge because the map and road signs disagree and they're all "going with the flow". Or to put it another way, if all your friends drove off a bridge, would you?
- f137 9y agoWhat would you do if confused by the road signs? A car could 1) see what other drivers doing 2) ask them - and this is easies with v2v 3) ask some central authority owe the air
