I have seen a ton of concept cars in my time, but the XSense by Shinsuke Aizawa is easily the most bizarre. Bizarre in a good way, mind you, as the three-wheeled vehicle is unlike anything I have ever seen before.
The XSense by Shinsuke Aizawa has two tank treadlike wheels in the front and one circular wheel in the back. The driver sits into the vehicle, which can then be lowered or raised depending on the driver's preferred style. The pedals appear to be in the same spot as a regular car, and the vehicle is steered in much the same way as a motorcycle. While the design of the XSense seems a little dangerous for today, it could be great for tomorrow as city streets get more crowded and conventional cars and trucks grow smaller.
