One thing that the USA needs is a 100% accurate MAP.
Build a new street, and update the master map.
Add bike lanes, update the master map.
Restrict travel (size, weight, etc), update the map.
There have been videos posted of ambiguous bike lanes with cars driving in them with a person behind the wheel. If it is all mapped out, then it should actually be easier for a computer to tell where lanes are than for a human.
Unfortunately, all the maps seem to have serious shortcomings. Rather than the government that is building and painting the streets updating the maps, it seems more up to people driving them to discover new roads.
