“Everything was displayed in red on the front screen, it was automatically parked, and the steering wheel did not move.

They gave me a $199.95 bill for finding the problem with my car. And they said they would contact me and let me know about the problem with my car in 3~4 days. I am an Uber driver, but I am currently unable to work because I don't have a car.”
