I've been waiting for higher automotive voltage for a long time. Way back I wished for 48V as it's double the 24V standard used in European and off highway trucks as well as industrial automation and -48V is used in telecom. Wires can now carry 4x power. But from memory there was a 50V safe limit that would complicate things as the 48V charging voltage exceeds 50V as does the nominal cell voltage. So instead the industry selected 36V and planned to migrate but it never happened. The reason being LED lighting and small more efficient electronics reduced the need for higher voltages. With EV's there's no reason to keep 12 V.
