Okay, don't pay attention to the earlier attempts at comedy, if you stick around you will see that they are only attempts and a good number of the members try, but you will also notice they keep their day jobs as electricians.
I don't see "severe physical damage" being applicable inside a carport. Any event that would severely damage EMT inside a structure would most likely do structural damage as well and bigger repairs than the electrical would be waiting in the wings

I think I see what your getting at, and I know in the building I'm in now everything below 10' and exposed was spec'd to be RMC. This was due to hi-low / porta-pony traffic. (Hi-low + RMC still = FLAT) It makes sense to me in some apps, however I doubt it's required?
I guess the yes/no for EMT would be up to the inspector as far as the "physical damage" aspect. You could probably use "creative placement" to avoid potential vehicle to raceway contact. Your inspector would probably respect / allow that? I would also be concerned about corrosion, if it's not painted. Exhaust is pretty corrosive stuff...

The UL White Book states, "Galvanized steel electrical metallic tubing installed in concrete on grade or above generally requires no supplementary corrosion protection." I have used a lot of EMT on the outside of homes and found out later that it will indeed rust. In a covered area like a carport or similar location, I would take a chance on EMT not rusting. This is from my experience when I actually was an electrical contractor and master electrician.
