Quality steel nails are expensive, roads are very plentiful, and sensors have noise. Also, staying in a lane is not the problem. Teslas and pretty much all other quality brands sold today do it already. The problem is complex behavior like merging and routing around obstacles (like a person changing their tire.) Cheaper and easier would be surveying and improving road markings. As for snow, well, my Tesla maintains lane position in snow fairly well, and gets better all the time. No magic nails required.

What a surreal read... where are all the cases of Tesla hitting stuff it clearly shouldn't, that no real sane driver would ever do? Also, 'maintaining position fairly well' is too low bar in situation where mistakes can and do cost lives. I am all up for people willingly do beta testing for Tesla they even have to pay for, but it should be clearly marked and explained as so in contracts. The thing is, most folks are not aware of this at all. As things are now, Tesla's and Musk's lies (this and auto drive) cast a pretty bad picture on morals of that company.

  Bb8 proposes that we should install magnetic nails in our roads. Bdamm counters that magnetic nails would help with lane keeping, but that is clearly not the part self driving cars have the most trouble with. As you astutely observe “ hitting stuff it clearly shouldn't” is the problem. Which magnetic nails in the road would not help even a bit. > 'maintaining position fairly well' is too low bar in situation where mistakes can and do cost lives Yes! And again. Maintaining position is the only thing magnetic nails in the road would help with. Bdamm was not arguing that the car keep lane position therefore it is good. Bdamm was arguing that magnetic nails would not help with the real problems. > What a surreal read That is exactly my opinion about your comment. Can you follow two sentences stringed together?

  > where are all the cases of Tesla hitting stuff it clearly shouldn't, that no real sane driver would ever do? Real sane drivers hit stuff all the time. Miscalculated takeovers ending up in frontal collisions (these can be really REALLY fucking nasty, two 3-ton SUVs @ 100km/h have a lot of potential energy), trucks crashing into traffic jam rear ends and squashing together a dozen cars in front of them, people mistaking stairs to a train station as a car parking ramp (this is a common occurrence here in Munich [1])... the simple thing is, as long as an instance of an object is on a road, one of the instances will eventually get hit by a stupid mistake of someone.
