A former friend of mine ran the security detail for a local community college.  For some reason the county bought a couple of Chevy Citation electric cars that no department wanted, a wise purchase.  (This is the same county that bought skin colored gauze for its EMT’s, but that’s another story)  My friend decided to take them on and use them to patrol the campus.  Reliable they were not, with its 20 car batteries under the hood.  At one point one had an electrical fire and my friend was “shocked” to discover that not all fire extinguishers are the same when he landed on his butt.  The Citation was a crappy car with a gas engine in it; it did not improve when electrified.
