Use a PEI 4 or 5 and ADA slip rating and it should be good to go. Personally I wouldn't want a textured 'plank' but I'm sure you could make it look cool. The tile will be 'strong' either way, make sure you properly mortar it and it should be good to go.
Here is the spec with the COF i don't know how it applies to ADA rating?. (I don't think it is very textured, but I since it is a garage I would use a floor scrubber and clean and get it real soapy when needed)
I think it will look really nice with a car
P.E.I. Rating IV has high resistance to abrasion and is suitable for heavy-duty residential and commercial floor installations such as entrances, commercial kitchens, hotels, exhibition and sales rooms with some dirt conditions
Impervious tile has water absorption of less than 0.5% for indoor or some outdoor use and is frost proof
C.O.F. greater than 0.50 is recommended for standard residential applications and is marginally skid resistant
Break Strength (lb.) 300 <- is this an issue?? 300 lbs without thinset under it?
