At 3:20 AM, this Tesla ran a red light and impacted a semi-trailer: Available about three months ago, I've enabled 'traffic aware' option that will not run a red light. It even comes to a complete stop at a green light unless overridden by the driver. Other reports are the NHTSA is sending an investigation team. Bob Wilson
I'll ask around but really don't know. Tesla could help by having a list or matrix of features. Here is one credible source: My Autopilot doesn't see traffic lights or stop signs, so I would have to guess it's either an FSD feature or requires HW3. Bob Wilson
It's difficult at this stage to even know if the self driving features were on ahead of the accident. I am more than a little dubious about the use of these features. My feeling is that they can lull drivers into a false sense of security which allows their attention to lapse. Self driving that is good enough 99% of the time is not good enough. Combine that 1%, driver inattention and that unforeseen circumstance and you have the recipe for disaster. If my next EV has auto pilot or whatever they're calling it I will be very cautious about using it if it can lead to attention wanderings. I would be happy with simply an adaptive cruise control which my current base model Leaf doesn't have. I have become a great fan of cruise control for reducing fatigue on longer trips. Getting back to the original collision it looks like that age old mechanical problem: "Loose nut behind the wheel"
