It appears a Tesla Model S car can float and effectively drive on water. Tesla CEO Elon Musk tweeted a video of a Model S car which was able to float well through a flooded tunnel in Kazakhstan. Musk also noted that the company "definitely" doesn't recommend trying this -- but still vouched for the availability of this feature. The Guardian reports: The car appears to power through the water using the thrust of the wheels turning in the water, as the bow wave laps over the car's bonnet. Most internal combustion engine cars are sunk in water when the exhaust becomes flooded, which is why serious off-roaders have big exhaust scoops leading to the roof. Electric cars don't suffer from that particular issue, but how the rest of the car will react is unknown.
