I understand your issue with these cars - they’re dangerous, and could kill people with incomplete or buggy software. I believe the person you are responding to was pointing out that even with the bugs, these are already safer than human drivers. This is already better when looking at data rather than headlines and going off of how things seem.
Personally, I would prefer to be in control of the vehicle at all times. I don’t like the idea of driverless tech either.
Honestly though, America is different and special. We have states the size of the some of those countries, and states with GDPs that eclipse most of the countries you listed. Local government is a completey different scale at some levels than any of those countries you mentioned. It’s important to remember we are all different, and that’s not a bad thing.
