After seeing the benefits of an electric drive train over an ICE, the next logical question is "if they are so good, why aren't all cars like this?". The following theories have been suggested for as to why electric cars have failed to take off:

• Manufacturer's Money: There is an incredible amount of money that has been invested in refining and promoting the ICE car as the mode of transportation. Moving to a completely new system of propulsion means that the investment in the old technology gets a diminished return. Similarly, manufacturers have spent the better part of a century working out how to make money off of cars that need fluids constantly refilled, belts changed, moving parts replaced etc. Changing to a much simpler electric drive train means that manufacturers can't make the money they used to in fixing the problems that their own cars developed.
• Oil Money: This theory is relatively obvious; electric cars don't use oil and oil is worth a lot of money. If electric cars ever take off there will be a lot of rich and powerful people who will inevitably lose out. Rich and powerful people have been known to do all sorts of things to protect their profits. There has been some pretty convincing suggestions that oil companies have bought out technologies that have threatened their way of making money, especially relating to electric cars. An example of this is the WaterFuel Corporation in Australia (technology bought by oil company) (More specific examples needed...). Oil companies can't make money off a car that you charge in your own home. It has also been suggested that the Hydrogen fuel cell, though much less efficient than battery EVs, is being promoted because it can still be refilled in the same way as a standard car, meaning oil companies can still make money off of them.
• Fear of Change: Electric cars are pretty different from ICE cars; they drive differently, they sound different, they smell different, you put energy into them in different ways etc. In many ways these differences can be considered to the advantage of EVs (e.g.. they sound quieter...) but people have a strange habit of sticking to what they are used to even if the unknown alternative is better. According to vehicle manufacturers there has not been enough demand for them to bring an EV to market but growing environmental concerns, fuel prices and the stepping stone of hybrids cars has paved the way for consumers to demand a better system; electric cars.
• Recharging: Operating an EV requires forethought. Once you have run your batteries down, you need to recharge. Unlike refueling for an ICE this will take more than 5-10 minutes and your refueling points will be somewhat limited. Because of this EV makes a great commuter and short trip vehicle, but would be considerably more difficult when you need to go further than one charge will take you.
