Video keeps showing up on [TikTok ](http://www.tiktok.com/t/ZT8vYsWq1/) of a Tesla driving partially submerged.
Why isn’t this a story of hairdryer meets bathtub and that dude in the back isn’t toast?

Other commenters have mentioned that water is not actually a good conductor, but the other piece of the puzzle is that the high voltage systems in electric vehicles are completely sealed. Even if that Tesla were driving through a pool of Very Conductive Liquid, there is no way for that liquid to make contact with the high voltage system.
Internal combustion engines require air from the atmosphere to operate, and they also require air from the atmosphere to be cooled effectively. Because of this requirement for air, there is no point in sealing the engine since there will always be at least one opening for air. This is why driving an ICE vehicle through water can be catastrophic.
