"Do the front engine car have an airborne glide to them?"
Only a few stunt jumpers have really concerned themselves with airborne stability, and they have not used streamlined shapes. Quite a few LSR machines have used vertical tail fins to move the center of pressure back relative to the engine mass. Once you add streamlining to a highway car, subject to a wide range of crosswind conditions, the problem is non-trivial. The center of lift likes to change when a wing stalls, as it will at some speed combinations.
Hydroplanes are also notorious for blowover accidents. If they were reliably stable in the air, they could be designed to barely touch the water.
There is no excuse for a land vehicle to weigh more than its average payload.
