I’m talking full self driving beta, not autopilot. FSD works on bad roads, car parks, any weather it can see in, including moderately heavy rain. It won’t work in heavy fog, but I won’t drive in that either. Autopilot has a long history of only working on highways which upped its safety, but also a history of working hands off and at any speed.

Also note that the initial beta was only open to the safest, most responsible, drivers according to Tesla data (Tesla have a lot of data on their drivers, many opt in to sharing everything in the hope of hurrying better automation) so the cars were very well supervised

I’m really hanging out for insurance data once this system is out of beta
