I have emailed him a couple times, we are actually pretty near to each other. I asked him about coming here and doing a drive, told him I'd buy lunch or something and that I wanted to see how his magic car did around here but he didn't respond to that one. I used to follow his videos and watch every one of them but I started to feel like (just my opinion) he has a pretty big bias sometimes at making excuses for the car and downplaying things, although I will say more recently he has called stuff out more. The more telling videos to me are ones that have his wife's opinion.
One of the intersections that it would run the stop sign it used to stop at fine then hesitate way too long to go but then randomly started running the stop sign after slowing a bit, then it would cross the intersection, then stop in the intersection before the crosswalk on the other side. This is on a 25mph road so it has plenty of time to see things coming. One intersection even has a blinking red light in addition to the stop sign which just boggles my mind why it can't handle this one (55mph road). One is a railroad crossing which the last time I tested it (55mph road) I slowed it to 35mph ahead of time to give it lots of time. It went past the stop sign and stopped directly on the tracks, middle of the car was on top of the tracks.
I still like to play with it and enjoy having it even though it can be really frustrating sometimes but again, I am not using it as something to take over driving from me, I'm basically enjoying it as a neat tech demo while it slowly progresses.
