US cities have plenty of left turns, except for in new jersey where they're frowned upon. However, there can be a long wait to turn left, depending on conditions, so it might not be more time to drive a bit farther but turn right more often.

The waymo cars have trouble with getting hit while making unprotected left turns because they drive very cautiously. Except for the time they hit a bus, because they somehow thought a bus would swerve to avoid them (although the then Google vehicle was being overly cautious and trying to avoid an inconsequential object in the road). All in all, I would rather the waymo style of overcaution and immobility than the Uber style of over confidence and ignoring of potential obstacles. However, I would currently still prefer mediocre to average human drivers on the road with me over a waymo.
