He claims that it not only veered on its own, but that it didn’t slow down after hitting the first post and that it hit 12 more barrier posts before he managed to stop the car manually. This has convinced me to install a 2-channel dashcam into any vehicle before I start using Autopilot. I'm not saying that I fully believe Mr. Pang and that I believe Telsa is covering this up. But if there is an accident, and Tesla is able to produce vehicle logs, I want to be able to produce evidence that is under my control. A dashcam setup with a second camera on the driver should solve that problem.
