A Tesla Model 3 owner is thanking his electric car’s built-in dashcam after the feature proved useful as evidence for a road rage incident that resulted in a multiple-car accident. A video of the nail-biting incident, which featured a frightening instance of instant karma, was recently shared on YouTube.

The Model 3 owner, who goes by the username Mid-Range Tesla Model 3 Adventures on the video streaming platform, noted that the driver of the offending vehicle, a BMW sedan, became enraged after he was called out for almost hitting the electric car in Lassen St & Haskell Ave, Los Angeles, CA. This resulted in the driver getting enraged, to the point where he reportedly attempted to pick a fight against the Tesla owner. As noted by the Model 3 owner in the video’s description, he decided it was best to ignore the angry driver.

This only made the BMW driver even angrier. Upon realizing that he was being ignored, the angry driver opted to spit and throw an object at the Mid Range Model 3. By this time, the Tesla owner was attempting to record the driver on video using a smartphone (the incident transpired before Tesla rolled out the recently-released Sentry Mode/Dog Mode/Dashcam side-video update). When the BMW driver noticed that he was about to get recorded on video, he promptly returned to his car and drove off — running a red light in the process.

Instant karma soon ensued. As soon as the BMW driver rushed forward, he ended up crashing with another vehicle. The impact, which reportedly resulted in the car that hit the BMW crashing into two other vehicles on another lane. Ultimately, the angry driver’s road rage resulted in an accident that damaged his vehicle and three other cars.

Fortunately, the occupants of the vehicle that hit the red-light-running BMW were unharmed following the frightening road rage incident. In a comment on the YouTube upload, the Mid Range Model 3 owner noted that he opted to stick around so that he could coordinate with the drivers affected by the angry driver.

“I parked far away so the guy wouldn’t take a second attempt at my car. Asked the three people who got hit for their emails and the cops. That way, I could forward them the footage that night once the car finished transferring it all to the USB stick,” the Model 3 owner wrote.

Ultimately, this frightening incident of instant karma proves just how useful Tesla’s built-in dashcam feature is in the event of an accident. Nevertheless, this also highlights the further improvements that Tesla can introduce for the system. Tesla could also enable recording capabilities for the rear camera, which would be useful in instances where the vehicle gets rear-ended. A more convenient way for accessing dashcam footage, perhaps through the Tesla mobile app, would also make retrieving and sharing dashcam recordings easier.
