In the future I invented a car that transforms into motorcycle. This car runs on either water, light or solar power. When there is no sun all you have to do is charge it up by exposing it to light or filling it up with water. This invention was very popular, almost everyone switched to it as their choice for transportation. For that, traffic reduced since the car turns to motorcycle. Our air got good again because the car release steam that cleans the air. No more gas and oil drilling.
