Anyone who's used a laptop away from the mains knows this only too well. In the electric car world numerous reports of reality being somewhat less than the display shows, or finding that an overnight stop in cold weather has drastically reduced the range, simply don't apply to conventional cars. If the tank is half full it will still be half full the next morning, and you know pretty accurately how many miles can be covered, for a given quantity of fuel.<br />Use of the heater doesn't make any difference, and aircon takes about 5% more fuel, unlike an electric car, where use of either can reduce the range by 30% or more.microdavehttps://www.blogger.com/profile/01352078582764696261noreply@blogger.comtag:blogger.com,1999:blog-627081175329856970.post-80726917804919745452013-02-25T20:45:33.232+00:002013-02-25T20:45:33.232+00:00There's also the fact that to get an effective...There's also the fact that to get an effective amount of charge at a supermarket or motorway service station you'll have to park for longer than the usual two or three hour free parking period.

"lightweight" and "small" are the opposite of what reality is: Battery-wise. Something lightweight does not have the mass to store a decent charge. The thing also not mentioned is that the preferred battery is the Lithium-ion, which readily burns when punctured.
