Cruise (now part of GM) also relies heavily on maps, based on a talk I saw their lead CV guy make. It does make a good deal of sense - maps (at least street-maps) are mostly static and they make the problem way easier, so why not use them. In fact, most people these days are implicitly using maps - how often do people drive to new places without GPS navigation? Of course, vision and likely ML are still a necessary part of the equation.
- deepnotderp 10y agoBy maps I mean high resolution 3D maps with lidar and stuff as this startup seems to be doing. I don't doubt that 2d maps would be needed like how humans drive with a GPS.

I'd argue also they're using maps in an even more fundamental way - most driving occurs in places where the driver has already been, and relying on a wetware-stored map is a critical part of safe and effective driving. Local knowledge - traffic patterns, weird traffic signal setups, difficult lane changes, etc, is pretty critical to driving well.
- yeukhon 10y agoIf I have been to the destination multiple of times, I usually don't open map, I leave my phone off, or I let Pokemon Go running. But sometimes I do use map to seek for alternate faster route if I am in a hurry even if I am familiar with some alternate routes just to be sure. Since I don't use Waze (horrible experience), Google Map won't tell me there's a camera ahead, or police is ahead.
- potatolicious 10y agoRight - I may have phrased my point badly. The idea is that all effective driving relies on pre-mapping, either via digital means (your phone) or human means (your brain). The expectation that self-driving can be perfected without any kind of pre-mapping and the system can behave at high reliably in-situ seems unreasonable. Even humans can't do that.
- cfreeman 10y agoHumans and computers have different strengths though. Just because humans can't do something good doesn't mean computers can't, and vice-versa.
- p1esk 10y agoA map in your head is closer to machine learning than to using GPS.
