A Tesla Cybertruck sinks in a Southern California harbor

Elon Musk tweeted in 2022 that the Cybertruck "will be waterproof enough to serve briefly as a boat." But a Cybertruck did not float in Ventura Harbor.

@ai6yr interesting concerns about lithium ion batteries and salt water. It's a controversial topic among boaters. I have a friend who swears by them (to be fair I think he uses LFP and he says Tesla is using those in Malaysia), but most of the people I've talked to are terrified of them (you might even suspect that sailors are "superstitious")
@swart I know people are fans of LFP, but I agree on the hesitance to adopt anything with "Lithium" on it... given the tendency for those to be fairly catastrophic fires, and catastrophic fires on a boat are very bad
@ai6yr worst thing that could happen I expect, certainly worse than sharks :)
@swart Yes, sharks are better than fires on boats, by far. At least you have a chance with the sharks!
