Using a non automotive node is a viable option. For cold environments, the obvious solution is to provide a heater that keeps the computer at the minimum safe operating temperature. If it is -40C outside, a small amount of power can be used to keep the computer warm. Worst case, if the system was in cold shutdown at -40C, would be a warmup time in the 5 minute range before FSD was available. It probably takes longer for the heaters on the cameras to defrost the lens covers.
On the high end, various cooling approaches can be use to keep the chip cooled.
Automotive grade parts are needed in an open engine compartment or tail light assembly, but not for the FSD computer.
