We regularize traffic more than your estimate though. Like 99.99% of the 300 mile drive I took yesterday was sitting in a lane.
The hardest part was that Google hadn't mapped a service drive, so it thought the adjacent service drive was the best route (which would be addressed pretty fast if you were trying to deploy self driving service in that area).
I don't think we get to level 5 very soon, but level 4 cars will have the ability to go lots of places pretty soon. If I overestimate driveway distances from yesterday, it's like 99.966% lane miles. There was some construction, but it was already well marked for human drivers.
