CNN Business has an article on Waymo today. https://www.cnn.com/2021/10/12/tech/waymo-one-year/index.html
Doesn't sound too good me. After almost 10 years, still can't do many basic driving maneuvers very well. And in a very controlled test environment. How could it ever handle ordinary roads and streets with their almost infinite possibilities of unexpected road and weather conditions.
Meanwhile, Tesla Full Self Driving has a waiting list of pre-paid customers chomping at the bit. I'm one of them. One poll shows: 17.9% (17) have FSD 82.1% (78) waiting on FSD Unlike Waymo, FSD is open-road both urban and highway. It is available to just about any Tesla since 2019, possibly earlier. Bob Wilson
https://insideevs.com/news/540730/waymo-cars-overwhelm-california-neighborhood/ Pretty funny There are companies that provide the info that google and apple use for maps software, and the procedure for reporting errors is a bit byzantine, I tried a few years ago when the gps were telling people to take an illegal left across highway traffic and I gave up.
At one time, AutoPilot used only Google Map for speed limits. Like you, it was all but impossible to update and I never was able to get the default, neighborhood speed limit of 25 mph to work. After AutoPilot added reading speed signs and speed setting Traffic Aware Cruise Control, the local problems were resolved. There are Google Map problems like trying to navigate to the Astro Dog Park that wants to drive over a creek that has no bridge. So we use the navigation system as a 'suggestion' and things work better. Also, a recent subdivision added a new route to our home. The Tesla now shows the short road but navigation won't automatically use it. Once I manually drive over the short segment, no problem. Bob Wilson
