'Managing supply-chain challenges'... ?
Tesla is 'managing supply-chain challenges'. You can't even thumb-a-ride on a mule-team.
Modern cars are basically computer controlled, with loads of sensor connections. EVs will be as much or more so, so as to control capacity usage and manage charging (as well as other functions in common with conventional cars). Big Car creates a critical mass that hurts EV manufacturers in two ways:
* Big Car caused the creation of microcontrollers (the "computer") whose functions and capabilities suit the requirements of gasoline engines and emissions systems; EVs have different functional requirements and very different microcontrollers are needed;
* Big Car has the volume and purchasing power to get what they need from semiconductor companies; EV manufacturers get left-over capacity,
if there is any to spare, which, currently, there is not.
