Just the opposite of GP's opinion, I think basing the statistics solely on Telsa will half the figure rather than doubling it. Suppose the average interval of accident is t and the average speed of car is v, as Telsa cars only represent a small portion of all vehicles, we have
- Only Telsa: distance_travelled / num_accidents = v t / 1
- Two cars involved, but counted as one accident : distance_travelled / num_accidents = 2 v t / 1
You're doing that the wrong way, aren't you?
If 479k is total miles across an average of two cars, then the single-car equivalent, the number you'd compare to the Tesla numbers, is 240k.
It doesn't really make sense to adjust the Tesla numbers to do the comparison, but if you did you'd be doubling them, not halving them.
> We cannot translate this to miles per accident comparable to Tesla, because commercial traffic tends to drive more miles than passenger vehicles do, but there are far less of them, etc.
Neither of those reasons makes them incomparable.
