Bucket car
You may have your own opinion on the futuristic car. One of the most popular trends is that cars driven without oil. Beyond the basic common idea, shape is the most significant point. Maybe the shapes are out of your imagination, but you have to admit that, in the era of rapid development of technology, nothing is impossible.
This concept car called Ozone gives us a good example. I think I am gonna be like clothes rolling in the washing machine while driving. Its two wheels are driven by separated motors which are powered by fuel cell.
