Drivin' through cold is a problem too.
Most metals have a DBTT(Ductile to brittle transition temperature) where at a certain temperature, usually pretty low, the metal can no longer endure the same stresses it could before. In fact, it breaks like tooth picks. We did this in lab putting metal in liquid nitrogen and it cracked with 1/4 of the force.
That's actually the real reason the titanic sank. The engineers were dumb and didn't use materials that could withstand the temperatures of the cold ass water. Once the first compartment flooded, the rivets that held the compartment walls up just started popping off under the pressure.
Ok, enough blabber. Sorry. hha
