Kinda like those people who hate Semi's 'cause truckers 'always intimidate the little car'. 
When battery technology reaches the point where quick charge transfers can take place, ...
I don't know why some people think there are still great advancements in batteries yet?
Just dont get into an accident and short out your supercap... It could produce a "bang" that would put a movie gas tank explosion to shame.Check recent developments in "ultracapacitors" or 'super capacitors."

Saying goodbye to batteries
Researchers at MIT are developing a new device that has the potential to hold as much energy as a conventional battery but could be recharged in seconds rather than hours, would last almost indefinitely, and won't mind the cold. The device could prove the first economically viable alternative to today's battery. It could one day yield a practical all-electric car and provide electricity storage critical to using intermittent energy sources such as solar and wind.

The ultimate clean and cheap energy source is the sun. When battery technology reaches the point where quick charge transfers can take place, higher storage capacity, etc., batteries charged from solar panels or wind turbines will convert solar energy to motive energy. Battery research and development is not standing still, the costs of climate change are driving this effort, however indirectly.
It is short-sighted to assume that batteries are, or can be, only charged by burning a fossil fuel somewhere other than in an engine. It just ain't so. At current solar PV prices, it is easy to achieve equivalent fuel costs of 50 mpg in an EV. The technology is not even half-mature yet.

I don't know why some people think there are still great advancements in batteries yet? There is a max amount of energy that a battery can store per pound of battery and that is it. There is no way to engineer a battery to do the equivalent of pouring 25 gallons of gasoline into a 5 gallon tank.
Rapid charging and rapid discharge is limited by heat. Forget about low cost reliable battery banks that can be rapid charged in the time it takes to pump 20 gallons of gasoline.
Don't go thinking there are technological breakthroughs in solar panels just around the corner either. 10 square ft of solar panels flat on a car roof isn't going to charge very much either. Ever look at the dismal performance of the light weight solar go-karts the students build for cross country races.
Solar panels and wind turbines? Obviously the eco renewable energy wizards do not ask about the impact of solar and wind turbines on the national power grid. Last time I checked people drive in the daytime and park at night. Where is your solar charging? Wind power is unreliable and must be backed up with gas, coal or hydro-electric.
An electric car owned and used by a well paid engineer who owns tools,resides on a rural estate having solar panels and a wind turbine is one thing. Joe above average $45hr living in a small town or city is another matter with an eco vehicle is another. Then there is Joe average $25hr living in rural areas and must travel longer distances on lower quality roads.
If you want clean energy. Use abundant natural gas and convert it to methanol via nuclear steam.
Don't underestimate the acceleration of the Prius. The electric motor has high torque and it kicks in when you put the pedal to the metal and has no problems passing on a hill or on the freeway. The inside room of the Prius is the same as the Camry. It just looks smaller, so it can fit 5 no prob. It is classified as a mid-size sedan, not a compact car (except for the Prius C).
