Floating isn’t the only extreme condition Tesla has prepared for. Its Model X SUV has a “bioweapon defense mode” for its air filters. Looking at the other car and truck in that video, it doesn’t seem like it went through much more than a foot of water. High speed + low car make a wave go over the hood, but it doesn’t look like the tires ever left the ground. CSB: I drove through deep water once, deep enough that my car was floating. The engine didn’t stall, and I manage to paddlewheel through it. Didn’t have much steering or acceleration, and the car was bobbing like a cork the whole time. Did an oil change when I got home. Looked like chocolate milk. Was an early 80’s lightweight car, and wasn’t worth more than scrap value, running or not.
