Driving on a planet with an atmosphere of NO2?

Almost mandatory forced induction, exploding head gaskets, destroying valvetrains, impairing PCV function, straining fuel delivery, much larger required spark, extremely sensitive timing, and carrying heavy breather gear for the occupants...?
 


Yes, I know about nitrous oxide injection.
That is a small percentage of the actual gases going into the engine.

An atmosphere of pure NO2 results in the obvious drawbacks that amtseung listed above.
