Definitely not everybody are on SiC parts, let alone MOSFET only designs. Though, the trends is for at least some hybrid SiC parts as they are getting cheaper.
When switching speeds are low enough (as is in EVs,) you don't need that much switching performance. Current Si IGBTs are quite viable in EVs, if you switch high enough voltage.
There is a reason why rail is still preferring high voltage AC for traction. That's because Si IGBTs for that are cheap, and efficient enough.
