> First of all. Tesla counts the number of miles for every Tesla being involved in an accident. The other figure you quote is for all miles driven by motor vehicles before getting involved in an accident. Given that accidents tend to involve two or more vehicles the number of miles traveled before an accident involving a Tesla without autopilot or safety measures would be closer to 820.000 miles.

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.

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
