Thanks for all your responses. The accident took place on a city street.
Both insurance companies are still factfinding (there were no witnesses) and I won't worry about fixing it until after the dust has settled. siai47 already provided me with a lead for a replacement door. For now, I'm not too concerned as the door is fully sealed and the car is otherwise unscathed.
Regarding autonomous cars: I'd be willing to bet the present Google car would pass a driving test with flying colors! With Tesla saying they have over 130,000,000 miles already racked up using AutoPilot and Google having many years of everyday driving data on 30 cars (that I see daily), between the two of them there's a wealth or real-world data to digest. Wish they would band together.
Every Tesla owner with AP that I know would not part with it for the world and they all credit AP with helping avoid fender-benders. I've put on about 500 miles on others' Teslas with AP, and would have loved it on mine but I wasn't willing to shell out the $$$. Just have to understand AP's present limitations and, judging by some of the stupid YouTube AP videos, maybe an IQ test for the driver should be a prerequisite.
Hmmm, I wonder if Tesla's AP had been implemented in the i-MiEV, if this accident might have been mitigated? Basically, it was a very shallow left-hand curve in the road that the lady failed to negotiate and simply drifted into the right lane and sideswiped him. The SUV came from the left rear of the i-MiEV, so I don't know if Autopilot could do anything about that, and the sideswipe caught my guy completely by surprise even though he was well aware of the SUV's presence in that quadrant.
