In the face of a devastating Hurricane, Musk promised that the Cybertruck would be an amphibious vehicle.

"Cybertruck will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes and even seas that aren't too choppy," he said.

A pickup truck with four wheels is not an ideal vessel to cross a body of water.

Now that he has a new idea, Musk has been thinking a lot.

"You would need an electric propeller mounted on the tow hitch to go faster than a few knots," he said, after another user suggested the Cybertruck may only be able to crawl between three and ten knots.

It's a great idea to think about.

It's a vision that only exists in Musk's mind.

Considering the company's fit and finish issues, we're not sure if the Cybertruck is waterproof.

We will always believe it when we see it.

The Cybertruck will double as a boat.
