While playing single player the other day I had an idea, Cars in Minecraft. Here's how they would work, they would look like mine carts but they would have headlights and a little steering wheel and maybe a bit longer then a mine cart and can hold 2 people at a time. they can only be "driven" on cobblestone or some other material and they wouldn't go very fast but they would be a little bit faster than walking. and i was thinking that to make them it would like mine cart in the middle square, then on each corner would be like wheels that you can make separately, then a piece of redstone, and then a stick somewhere. I don't know exactly but i think that it would be pretty awesome.
Cars?
