I work for an insurance company that specializes on auto insurance. It'd be filthy rich if people only had an accident every 300,000 miles.

The company is pretty well off, but pays 95% of the premiums in claims payment.

Doing a very back-of-the-envelope calculation, 22.5% of our insured cars had a claims payment this year (august to august), so an average insured person has a traffic accident every 4 years or so, and does way less than 300,000 miles every 4 years (more like 100,000 being generous).

I was saying not that it wasn't better than average but that it wasn't amazingly good. I'm pretty sure my mom has gone 300,000 miles between accidents; (growing up, we went on a lot of road trips.)

all I was trying to say is that I think the best human drivers can pull off three hundred thousand miles; it's not inhuman. and that's what we are going to need for self-driving cars to become widely accepted; something that would seem impossibly good to a human. And I bet they will do it, eventually.

I was responding to

>My suspicion is that the figures quoted around these Google cars and their safety record, if you take them at face value, lead to a ludicrous level of optimism.

and I don't think 300,000 miles without an accident is a ludicrous number; it's something a human can achieve, (even if it's something most humans don't.) It's a milestone, sure, but like I said, for self-driving cars to be accepted, they can't just be better than the average driver; they need to be better than the best drivers.

Ah, ok :) , I hadn't understood your statement correctly.

I'm looking forward to self driving cars because of their convenience ! Imagine being able to sleep during road trips, using them as a taxicab for places where there's no parking (and ask it to park itself :) ), sending them to pick up somebody... the possibilities are endless !!
