Under the Chassis: A Look At Tesla's Battery Shield
cartechboy (2660665) writes "Tesla said a few weeks ago it would add additional safety shielding to protect the battery of every Model S car on the road against damage from road debris. But it offered no photos of its update as it would look when installed--so one owner took his own. These may be the first detail shots of what the three different pieces look like. There's a half-round aluminum tube, a titanium plate, and a T-shaped section--and you can see how they combine to deflect and direct impacts to minimize damage to the battery. Do these updates look like they'll solve Tesla's problems?"
The sample size of total number of Tesla's is statistically significant. Total size of population relative to ICE vehicles is irrelevant.
But # of fires per vehicle mile driven can be calculated and the figures normalized. The Tesla sample size of 10K + cars is large enough to be statistically valid.
