“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. Re-graded missed (2026-07-05 audit): there is nothing genuinely contested here. No boat capability ever shipped — Wade Mode (32-inch depth, brief shallow fording) is explicitly not boat mode, and real-world attempts ended with a Cybertruck stuck in a river (Apr 2025) and one disabled and taking on water in Grapevine Lake (May 2026). A clean miss, not a dispute. Electrek — Cybertruck disabled in Grapevine Lake, May 2026 ↗

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.
