Even though there's a mandate for driver controlled passenger doors, they either don't work right, or the driver was actively at fault. (I assume) that cab doors are the same as all modern cars and automatically lock when the car exceeds 3mph. If so, the rear doors would still be locked when the cab stopped. In which case the driver would have to actively unlock the door for an exiting passenger.

I don't know if drivers can selectively unlock the left or right door, but if that feature doesn't yet exist it should.

Giving drivers active control is important because it eliminates the "he jumped out before I could react" excuse.

BTW- drivers also benefit from passenger doors that stay locked until unlocked. It would be somewhat intimidating for those considering robberies or assaults against drivers.
