I brought up the same point last week (https://news.ycombinator.com/item?id=6703967) and the Model S appears to be 25x more likely to catch on fire: https://news.ycombinator.com/item?id=6704111
Right now your link goes to someone else making that claim with no source and no work shown.
If you want more fun, run the traffic fatality rates since June 22, 2012. Tesla is currently sitting at zero (it would be highly unrealistic to expect that to last).
