What idiot sees a flooded underpass full of stalled, almost floating cars and just drives on in?
I'm pretty sure he just voided the warranty on his Tesla.

Huh, I would have thought electric cars and water would mix a lot worse than that. Did they engineer it just for the possibility of flooded roads or is it a fluke of the car's design?

The S has a biodefense mode option. The cabin becomes somewhat airtight if you activate it. Also, the battery pack is sealed vs leaks or water.

Musk tweeted in response: We *def* don't recommended this, but Model S floats well enough to turn it into a boat for short periods of time. Thrust via wheel rotation.

Yeah, the battery pack would catch fire if exposed to water, they must have to seal it pretty well.

And yeah, as already mentioned the passenger compartment has a "bioweapon defence mode", presumably because Elon Musk is actually a real life Bond villain and he wants his customers to be safe from whatever doomsday scenario he has planned.

I'm not really sure what happened there, the camera work was hard to follow

Tesla Easter egg - how to make your Model S submersible has been added as a related post - related requested by Zawash.

I don't see any floating. The Tesla is just much heavier and denser than those other cars, and can maintain traction with the ground. And no ICE to ingest water and die.

In Russia, if you haf $100k automobiles, you must still use potato phone.
