Feeling a little paranoid today? Fear not, they are talking about vehicles with gasoline engines and battery. Battery for short trips, gasoline for long trips. Keep your gas tank full and you don't have to worry about the battery level. It you are afraid of using grid electricity, never plug it in, it will still get better miliage than a standard combustion vehicle.

Computers are very fast and storage media is very cheap. Do computers stay current longer? No because software is not concisly written to save a 3-1/2" disk per sales package by putting the program on three instead of four, but a bunch of memory eating crap is dumped onto a cd or dvd. Ergo it eats up hard drive space and hogs memory.
If we did buy into this electric boondogle the government will see it as another way to control us and we will save nothing. The government will see that we never have "extra" money.
