It gets about three time the mileage when driving compared to flying - a small reminder of just how energy efficient it is to let the normal force from the ground hold something up compared to expending energy to do so.

As an example to disprove the rule, the Grob G 109 motor glider[1] goes 1500 km (vs flying car 1315 road range) on the same amount of gas while probably going faster (180km/h economical cruise).
