I am wondering how many people instantly know it is safe to go in the water where a Tesla car is submerged. You will not be shocked by the battery. Initially, I thought it was obvious for people, but now I have second thoughts. So it is not going to shock you even if the terminals of batteries would be exposed (of course they are not) because the current will go between the terminals of the battery. Also, think: maybe it’s dangerous to wash a Tesla car; you know it’s electric? Or drive in the rain?
