You have to pick:

I suspect one would not survive driving through a puddle at high speed.

Also it could be very dangerous indoor. One accidental splash and you are sportscar in a hallway. That can't end well.

Let's say that "warm" and "cold" in this case means "icewater" and "almost painfully hot", to make the circumstances a little less likely to happen by accident.

This would be problematic when someone flushes the toilet while you are in the shower.

Depends on how hard the punch is and if it breaks any bones or destroys an eye... Meh going with the other choice.
