Ahh we need stereo on Mars as well!! Great observations, I never thought so much. Thanks for sharing your views.I think the real issue would be the very low atmospheric pressure, causing most liquids to boil off-steering and braking immediately impacted. Lubrication, seals, and gaskets would be the first serious problem (after converting to electric power) followed closely by the extreme temperature swings. Stereo performance would be heinous without some type of shielding, and paint and fender flares would really suffer from UV damage, not to mention interior materials. Low gravity means recovery would be interesting, suspension springs and damping would need a serious re-think so you don't just bounce all the time like a ball, four mini-tracks would be much better than current tire choices, or solid, extremely wide rubber tires might be better, depending on terrain.
A fun few minutes of engineer-y thinking. Back to work.
