Controllable Cars in Minecraft (1.8)

This set of commandblocks change your everyday minecarts into controllable cars. Note that this is just a concept and it's far from perfect, though it's good enough for you to enjoy and mess around with.  Feel free to copy this into what ever world you want cars in. But be warned, this breaks some survival aspects such as the hungerbar and health. Remember to give some credit in any video, but other than that, ENJOY! :D

If you copy the redstone you NEED to type in these commands in the chatt. Since it uses some scoreboard stuff, the scoreboard needs to created on the new map. 

Commands:
/scoreboard objectives add jump stat.useItem.minecraft.fireworks
/scoreboard objectives add start stat.useItem.minecraft.porkchop
