A dimwitted driver “intentionally” plowed his Cybertruck into a North Texas lake while attempting to test out the electric vehicle’s “Wade Mode” on Monday, police said.

A bemused bystander watched on in apparent glee as the driver and his co-pilot inched off the rocky shore at Grapevine Lake.

“Yo sir, you can’t park there,” the witness mocked as the Cybertruck quickly started to take on water, according to a video obtained by Fox 4.

The driver and his passenger made it a few feet into the lake before they appeared to strike one of the shore’s many sizable rocks. The two men tumbled clumsily out of the passenger side window and waded over to a nearby dock, according to the video.

The Grapevine Police Department said that the truck “became disabled” moments into the driver’s short-lived seafaring attempt.

The driver, who wasn’t publicly identified, admitted he “intentionally” steered his vehicle into the lake to “to use the Cybertruck’s ‘Wade Mode’ feature,” according to the police department.

Wade Mode is one of the Cybertruck’s four off-road features. It is supposed to work in shallow bodies of water, including rivers, but does not activate automatically, according to the owner’s manual.

“We want to remind drivers that although a vehicle may be physically capable of entering shallow freshwater areas, doing so can create legal and safety concerns under Texas law,” the police department said.

Authorities used a crane to hoist the waterlogged Cybertruck out of the lake later that night.

The driver was arrested and charged with operation of a vehicle in a closed section of the lake, not having a valid boat registration and other water safety equipment violations.
