I am glad it looks like Waymo is taking safety seriously. If they are getting into fewer crashes (serious or not) that is a good thing. It is worth remembering, imho, that the ability to avoid a crash, whoever is at fault, is an important skill also. I hope they keep working at the self driving and continue getting better with their safety record.

I also hope they figure out how to keep the wheels from falling off. How did this happen? Does it happen often (to any class of vehicle)?
