This seems accurate to what modern car underbodies look like, a smooth underbody is very important for aerodynamics and therefore fuel efficiency. For race cars it is often even more important not only for fuel efficiency but for downforce.
Also rust protection. Northern cars just having the floor fall out is less of a thing.
why northern? I thought the Southeast was more prone to rusting as the Mexico Gulf is right there?
Probably salt on roads. Sea air kinda rots everything, salty roads just the bottom.
that makes sense, my southern brain didn't even process that road salts could cause corrosion haha
