Traffic tools renewal

I think Minecraft could add a black rubber slime. It would work just like the regular slime, but it drops rubber balls. These rubber balls can be crafted into rubber blocks that negate fall damage, as well as tires and seats. Slimeballs could be used to craft super glue. With some additional parts, players could build their own vehicle body using blocks, then glue it all together with super glue (including tires, an engine, and a driver's seat). A tool could be used to pick up the vehicle and store it in the inventory, and the vehicle would have a collision box.
