I'm not entirely sure if services like robotaxi are ultimately good or bad. I think it greatly depends on how they are deployed and regulated.

If they governments don't force company's to ensure they make constant improvements and innovation as well as making them cheaper then I think there could be a serious problem when non driverless vehicles are outlawed, making robotaxis the only viable way to get around in car dependant places, companies like waymo will enshitify the hell out of robotaxis making them way too expensive and just barely safer than normal cars in order to rake in the profits as much as possible. I feel like this is a concern in the US especially due to there idea of a "free market" with very little regulation.

On the other hand if companies are forced by regulation to constantly make cars safer and not cost too much then I guess robotaxis could be improve road safety, congestion and a few other problems but by no means fix them.
