Sorry, I can appreciate some devil's advocacy, but I'm just not buying it here. Assuming the Tesla employee was unarmed (which I think is a safe assumption), then there's nothing potentially dangerous enough to justify running someone over rather than wait the few minutes for law enforcement to arrive. Even if you think you are being falsely imprisoned, I don't think you are justified in running someone over rather than wait a few minutes for law enforcement if you are not in immediate danger.
You are assuming that the 'running someone over' was deliberate. We don't have enough information for such determinations. It may have been accidental, or more likely criminally negligent, but we shouldn't assume deliberate attack without all the facts.
We do have them hitting two different people on two different occasions. That's not iron-clad by any means, but it is evidence that weighs against the accident theory.
One detail is that Tesla alleges that they 'accelerated' in reverse. This is completely abnormal and if it can be corroborated by the physical evidence, it will be very troublesome for the driver.
Further, I have to believe that Tesla has no shortage of people who know about accident reconstruction and who can determine the idle speed & mass of the jeep and compare that with the force needed to cause skid marks or to have knocked the employee whatever distance. If they were to do that, it would be very interesting because we all know just how skilled their engineers are, from Elon on down.
