I have recently got into a habit of driving wherever I want to go since I purchased an electric car ( it's actually a hybrid car) four months ago. I recorded the last date that I filled up the tank. That was February 25th. 200 Yuan for gas and 50 Yuan for charging let my car ran for near 800 kilometres. So, all my thoughts about electric cars have changed. They are not toys which many people think. This reminds me of the situation which cameras faced many years ago. During that period, more clear pictures were taken by cameras than phones . Most people still chose to buy digital cameras to take photos. But now, cameras have been almost replaced by cell phones. Nowadays, Canon or even Kodak, these brands are known for making other produces, but cameras. The glasses made by Kodak are great for preventing myopia. Of course, the technology or making glasses is related to making a camera. So, if the produces made by BMW are not cars in future, don't be suprise!
