These horrific deaths and injuries are tragic. I see too many schadenfreude comments here approving of people dying just because they chose to drive a vehicle most people don’t like. If there is blame, it is not on the victims, but on Tesla and the regulators we trust to ensure minimum and obvious safety features.
