Apparently the new generation of electric hybrid vehicles look too much like their gas counterparts, casuing consternation and hesitation in those who would respond to emergency calls.
Their concern revolves around the high-voltage batteries that power the vehicles; they can pack a lethal jolt of electrical current, and could be exposed in a crash. The cops, sheriffs, firefighters, etc. aren't sure they'll be able to tell a gas vehicle from a hybrid, and that they will therefore be exposed to additional personal risk.
It reminds me of the fears of health workers involving the potential of tainted blood in trauma victims -- how do you help someone when you fear for your own safety? Of course, there were solutions to that concern, and my hope is that there will be similar ideas implemented in this latest scare -- perhaps a window sticker? Or an RFID tag that would ping some sensor the emergency crews could carry?
