If you live where fires are prevalent like California, you might want a heat shield. In any case, without the heat shield, don’t park on brown grass.

I would suspect that depending upon the grass a car could catch on fire shields or not shields. That happened with an OK state trooper not many years ago after he chased a suspect into a field and bailed out for a foot pursuit.

Five minutes later the patrol car was going up in flames and became a total loss.
