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.

Probably salt on roads. Sea air kinda rots everything, salty roads just the bottom.

Salt only lowers melting point around 4°C, below is split. The occasional fire for heating the engine on the other hand…
