A brick is more aerodynamic than a Wrangler. Fun fact about bricks: they're rock types but some dedicated trainers have been known to make their bricks use the Fly move without ever using the HM.
I drove a jeep for 10 years. Terrible commuting/travel vehicle. The entire vehicle is a wind break as illustrated. You go above 70 and it's as loud as a jet inside. Very stiff clutch that made switching gears in traffic unbearable. Only good thing was the indestructible i6 engine but they got rid of that in 07. Still had use in socal with the soft top but I don't know why they would be popular in colder, less mountainous places.
