A beta version of Tesla's cyber truck has been spotted.

According to Elon Musk, the Tesla Cyber Truck is nearing production.

On Wednesday, a Tesla Cyber Truck was spotted roaming public roads; Instagram user ftronz posted a video and photo of the truck on Instagram.

Musk has confirmed that the production truck will be slightly smaller than the concept unveiled in 2019, and this early production prototype appears to be consistent with that comment.

Aside from minor design adjustments to meet federal regulations, such as side mirrors, the trucks spotted on public roads have a nearly identical design to the concept.

The video was reposted on Twitter user DriveTeslaca, where Mask confirmed that the side mirrors are removable if the owner chooses to do so, while noting that "many small adjustments to make it better" are still being made (presumably for off-road driving). The executive confirmed that the prototype is very close in design to the production version.

Notably, the prototype does not have a third brake light, which is required by the federal government. It is possible that this prototype simply does not have a full-width light bar or that it has been disabled.

Production of the Cybertruck was originally scheduled to take place in late 2021. Due to delays, production is behind schedule; in 2022, Musk said the cybertrucks would begin production in 2023; in January, during a quarterly update conference call with investors, Musk said the cybertrucks would not be delivered in significant numbers this year and would begin production in 2024.

In a call with investors, Musk revealed that the cybertrucks will feature four sets of Tesla's next-generation hardware for safety and driver assistance features. It is unclear whether the range-topping cybertruck will still feature four motors and four-wheel steering.
