Re: Safety rating

You're right on the money, naperlou. Yes, Tesla has "fives" (best rating) across the board in NHTSA's safety ratings. And, yes, the methodology for the ratings is well established. I agree that the ratings agencies don't yet have a handle on how to characterize the relatively new phenomenon of lithium-ion failures.

Re: Battery quick-release drop in case of fire emergency

That's an interesting idea, Ken, especially in light of the fact that firefighters had so much trouble extinguishing the battery fire.

Battery quick-release drop in case of fire emergency
Ken Sides   10/4/2013 12:31:10 PM
Since the Tesla Model S batteries can be swapped out in a few seconds at their roadside stations, there must be some sort of quick release that would make it possible in an emergency to drop the battery pack and roll the car away from it, thereby saving the vehicle in case of battery fire. 

Perhaps there should be a small, separate battery just for the purpose of driving the vehicle a few feet to get off of and away from the dropped main battery.

Chuck, Didn't Tesla get a top safety rating just recently for the S?  This is a problem with EVs (and hybrids) that use Lithium Ion batteries.  I am not sure that the testing agancies really know how to characterize the failure modes of these batteries.  As I have mentioned before, there was an incident in China where an all electric cab of local manufacture caught fire and burned up the driver and passengers completely after a collision with a car that drove away.  This is very worrisome.
