Cybertruck can cross rivers, lakes, seas

“Cybertruck will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes & even seas that aren't too choppy”

What actually happened

Still disputed. No 'boat mode' or certified water-crossing capability has ever shipped, and multiple owner reports of water-stranded Cybertrucks stand unrebutted. No new developments found in 2026 reporting. Wikipedia — Tesla Cybertruck (boat-mode claim and aftermath) ↗

The prediction that the Cybertruck can briefly serve as a boat was unveiled in September 2022 with the notable detail that it will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes & even seas that aren't too choppy. Thousands of Tesla reservation holders are waiting for this feature, which enables travel from Starbase to South Padre Island across channels. This follows Tesla's pattern of ambitious vehicle predictions, such as enabling EVs to drive through water as demonstrated by other models like Rivian. The waterproof capability matters for practical off-road and emergency crossings in varied terrains.
