A man has been arrested in Grapevine, Texas, after intentionally driving his Tesla Cybertruck into Grapevine Lake to test the vehicle's built-in "wade mode" feature, which is designed to allow the electric pickup truck to pass through shallow bodies of water up to roughly 81 cm deep. The vehicle became disabled and took on water, forcing the driver and passengers to abandon it near the lake's southern shoreline, where it had to be recovered by police and fire department water rescue teams. The driver faces charges of operating a vehicle in a closed section of the lake and violating water safety equipment regulations, with police noting that entering bodies of water — even in a capable vehicle — carries both legal and safety risks under Texas law.
