Elon Musk went on Twitter today to claim that the Cybertruck will be waterproof "enough to serve briefly as a boat, so it can cross rivers, lakes & even seas that aren’t too choppy".
I don't know how much I believe this but If it's able to do that it would be very impressive.
It's probably not going to be much better than the wading depth of SUVs and pickups priced around what the Cybertruck range goes for. This is just another Elon moment that requires him to get very specific about what he actually means.
