Old Japanese sedan style taxis universally had a handbrake-like lever around front driver side door sill that opens rear passenger side door through a mechanical linkage. Toyota JPN Taxi[1] replaced most sedan cabs, and it has electric sliding doors which is nicer than swing-out doors. Already opens and closes with electronic commands from driver seat. No big deal. 1: https://en.wikipedia.org/wiki/Toyota_JPN_Taxi https://en.wikipedia.org/wiki/Toyota_JPN_Taxi
