Those work at +55 and at -20 as well. For too high temperature it's only a question of cooling sizing, bigger radiator and bigger water pump... for too low it's a question of how much electricity you use to warm up the battery. If effiiency/range is not a big concern (like in a rally car) this is not a problem. Certainly not compared to current cars with white-hot turbos and red-hot exhausts on full ALS running trough the length of the car (guess what makes the car go +55 on Acropolis)
c) Sure, that's just a technicality though. Check out what forces F1 crash structure can take and what size it is.
I like watching steam engines too... or sailboat racing for that matter. Don't have a problem watching EV rally car.
