Wy wife and I drove our Tesla Model 3 from Palo Alto, CA to San Francisco downtown, to meet friends. I was the driver, and my wife sat on the passenger seat. The weather was clear, and the pavement was dry. I did not engage auto-pilot features during the entire trip. The car condition was normal with no signs of error or warning. I made a right turn onto [XXX] from [XXX] Shortly after I completed the turn, the car unexpectedly lost control. Without any prior warnings, it suddenly veered into the center divider, snapped a tree, dashed towards oncoming traffic on the other side of [XXX] , and finally stopped on [XXX] , labelled as location A on the attached drawing. Everything happened so quickly: I could not control the steering wheel, and I applied the brakes in vain. The vehicle seized control, no matter how hard I tried to stop it. I regained control of the vehicle at the intersection of [XXX] and [XXX] , and was able to park the car at location A. We were very fortunate and blessed that we did not hit people at the bus stop, that there were no cars in front of us, that the opposite traffic on [XXX] was stopped by a red light, and that the traffic was light on [XXX] Without such luck, my wife and I, and probably others, would have been seriously injured, if not worse. Because [XXX] is one-way, we decided to move the vehicle to [XXX] , and parked at location B in the drawing. I called 911 and spoke to a female dispatcher. She asked us to remain at location B and wait for police officers to arrive. We waited there for almost 3 hours, but no police arrived. The dashboard display indicated that we had a flat tire(s). We called mobile tire services. After their inspection, most of our tires were alright, except the rim of the front-left wheel was badly bent, as you can see in the attached photo. The mobile tire service staff was skilled enough to carefully patch the damage and said it should be OK to drive back to Palo Alto.
