Video shows alleged Audi tech's joyride in customer's car

Dramatic video is raising new questions about what can happen to your car when you leave it with a mechanic.

A person posted dash-cam video, claiming an Audi service tech in Palo Alto, California turned a test ride into a joyride, racing at high speeds, and possibly even taking drugs in the car, reports CBS News correspondent Ben Tracy.

According to the GPS information embedded in dash-cam video, the driver raced down a street at speeds reaching 53 miles per hour, in what seemed like a scene out of "Ferris Bueller's Day Off," where garage workers hit the streets of Chicago in a borrowed Ferrari.

But in this case, there's a twist - the Palo Alto driver stops to take a break. That's when you hear him snorting.

He then takes off again, this time pulling onto a freeway and revving up to a speed of 77 miles per hour.

The general manager of Audi Palo Alto issued a statement saying: "An unfortunate incident was brought to our attention earlier this week. We immediately began our investigation and have already taken action."

When asked if the video was authentic, he would not confirm or deny it beyond his statement, and would not say whether the mechanic is still employed there.

Palo Alto Police told "CBS This Morning" they are not investigating this alleged incident. They also noted that the streets seen in the video are near at least two dealerships, which mechanics often use for high-speed test drives.
