I'm really skeptical of this theory being pushed in the article, without further data to back it up. Maybe the Model S has a higher claim frequency because its owners would be more nitpicky of their $100k+ car, than a $30k Leaf? Shouldn't there be other data showing that performance of luxury cars also leads to higher frequency claims?
Personally, I see a lot of Tesla's on the road every day, and the people who were used to driving a Prius or minivan, seem to drive their Tesla in pretty much the same manner.
While one could argue that Tesla drivers are, indeed, less picky than people who paid $60K+ for a real luxury car (if they were equally picky, one look at Tesla's build quality and they'd be off to a BMW dealership or something)...
But really, if we are talking about people driving 100K cars, we have to compare them with people driving other expensive cars, not a driver of a second-hand Leaf.
