At 3.18pm on 10 May 2018, Stefan Meier lost control of his Model S on the A2 highway near the Monte Ceneri tunnel. Travelling at about 100kmh (62mph), he ploughed through several warning markers and traffic signs before crashing into a slanted guardrail. “The collision with the guardrail launches the vehicle into the air, where it flips several times before landing,” investigators would write later.
The driver crashed, it doesn’t sound like it was in self driving mode.
A stuck pedal turns the steering towards the barrier? I think the driver had a stroke or heart attack and stopped steering
