Toyota have good hybrid cars, 100 % electric cars need charging points all around, so you can not use that car in real life. Plus also 100% electric cars are not 100% safe from electricity safety point.
When the time comes and I will definitely buy an electric car and not even because of savings because of the fact that this is the High Technologies of the future of mankind.
At the moment I would not say that electric cars are cheaper than conventional. They themselves are more expensive plus expensive batteries. Battery replacement is required once in 3-4 years. All that you save on fuel you spend on the purchase of a new battery.
