But they're still using easy environments. Not sure a German motorway without speed limits is easier to navigate than what Waymo faces.
I doubt that maximizing the miles between disengagements should be our goal. The goal should be for the car to face the worst conditions imaginable (snow, ice, dirt roads, other drivers ignoring traffic) and somehow manage to survive in those situations.
- Dylan16807 7y agoA limited access road is absolutely easier to navigate than a city. Once you can stay in one lane with sufficient following distance, you're done. The problem space is tiny.
- dx034 7y agoIf you have a lane. A gravel road with two way traffic (not that uncommon in rural areas) only works because drivers communicate their intentions (esp if one needs to wait at a point where the road is wider). They don't work by fixed rules.

- blub 7y agoA German motorway without traffic is very easy to navigate, but a typical day to day situation involves several kinds of cars driving at different speed limits and engaging in various maneuvers like overtaking, exiting, merging, switching lanes. There's also traffic jams or heavy traffic situations. If one wants to drive dynamically, one has to overtake and switch lanes quite a lot, which makes this challenging. If one is content with driving like a snail they can stick to the first lane, which is pretty simple and could be managed even by a so-called self-driving car.
- orloffm 7y agoThe usual roads are probably very easy, they have wide markings. The problem there arises with repair works which mess up the markings and lane width in all possible ways. During summer they are very frequent, and I bet they were the cause of human interventions in those old experiments.
- pas 7y agoNo problem, disengage there. The problem seems to br no safe way to disengage. Tesla crashes kill people because of this. (Ding ding, you have 1 second before impact.) Waymo probably wants to nail city driving first, because it's much lower speed, safer.
