I have a lot of respect for Waymo's approach to this. While Tesla and Uber have both just recklessly (imo) jumped in and started setting loose self driving cars and making bold claims, Google/Waymo has really taken a slow and measured approach and given great care to making sure their cars are actually safe.
Killing a few extra people today to bring self driving cars to market faster could actually save more lives in total. I have much more respect for Tesla for shipping something.
