The thread on the 100 mile car got me wondering. What would it take for electric cars to become attractive to some posters in here?
For me personally, I would like the car too:

Be able to maintain highway speeds for 300-400 miles between charges.

Relatively quick charge times...30-60 minutes? Enough time to eat and stretch a few minutes but not more than an hour.

Be comfortable to drive...AC, all that crap.

Priced affordably for the general public.

(I am in Canada and know this is the U.S. Domestic Policy forum - clarification before I get blasted)
For me the cost of Hydro would have to come down. Hydro One here in ON is the biggest rip-off, con-artist institution that we have. I live in the country and don't do a lot of day to day driving, but when I do drive, it is usually for a long distance. Therefore it is cheaper for me to fill up with gas (and we pay A LOT more for gas than you guys do) because my car is sitting most of the time. It is bad enough in the winter when we have to plug our vehicles in at night and then get the Hydro bill. I can't imagine having to do that all year!!!

i personally love to road trip, and frequently, so i think a back up battery is in order. also, they look so gay, why cant they look sporty or classic?

Many areas of this country can't get enough electrical power, during the summer, now. We have "brown outs" and "black outs" every year.

No one wants a nuclear power plant near them, nor do they want a coal fired generator, so just where is all this additional electricity, to charge thousands (or millions) of electric cars going to come from?

Answer that and you will have a big part of the answer to your question.

10 years?.... a more relevant question might include.....how long before we could recharge the batteries in such an automotive master piece ..... without foreign oil? Simply changing the propulsion technology of the automobile without an "in house" means of generating the electricity to recharge the batteries and fill the other needs for electric power ..... would be .....no solution at all. From my point of view we need to leave no stone unturned in the quest for a lasting solution to our energy requirements. Conservation (effiency), solar, wind and nuclear are the likely long term answers. Meanwhile ..... using our coal and all of the oil we can locate and produce can ease the burden of transition.

I'm politically incorrect and damn well satisfied to be so. Gummer

Solar or wind are the two viable methods for home generation of electricity.

BTW, 30 to 60 minute charge times are completely unrealistic, unless you want to connect a cable as thick around as your waist to the car.. and then have all the hair on your body stand up even when you're 5 feet away.

It'd be easier to have some sort of quick swap battery pack.

It would take massive copyright infringement against the oil companies

The answer is simple......

Give people everything they have now for the same price. Increased price is not attractive. Lower performance is not attractive. Higher price AND lower performance is a guaranteed loser! Unless of course socialsim mandates it.
