If your car ever gets submerged, in unbuckle your seatbelt, roll the windows down and once the water gets high enough in the car, you can open the door or climb through the window. This is pure panic from someone who should know better.

In an old car with crank windows, that’ll work. In a new car, the electrics have to still be working, and in a Tesla the OS has to still be running.

That’s why you need to have an emergency hammer with a belt cutter inside the car. Preferably one near every seat.
