If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
Cars have a large engine in the front and you have a gearbox, which is cumbersome. Electric cars don't have this problem. The motor is much smaller, the battery is below you. This will allow you to play with different shapes.
