Not so fast there
Before deciding that the truck driver caused the accident I would like to hear how fast the Tesla driver was going. If this is a 55 mph zone and the Tesla was going twice that (for example), then all bets are off. I find it curious that the speed of the Tesla hasn't been released at this point, at least I haven't heard it. Tesla company certainly knows that number. I'd be interested to hear from any Tesla driver whether or not you can use the autopilot mode to exceed the posted speed limit. I'm thinking that a properly functioning autopilot would obey the speed limit just like it obeys a stop sign. Or would it? I'm genuinely interested to hear.
