I would think getting another car that is efficient or electric as a commuting car or for short trips to the store would be a practical option for most people in the next 5 years. It's not going to happen overnight (our power grid couldn't handle it), but we need to come up with a plan for how the nation can cut it's oil use by 50%.
But, I understand the economic side of it. It costs a lot currently to buy all the electric vehicle components compared to the amount of gas/petrol that you would save. I could save between 200 - 300 gallons per year, but that is only $800-$1200. It would take 6-8 years for it to be cost effective right now at the current price of gas.
