Idea for a new support (The Rift Mechanic)

I am not sure if this has idea has been posted before, but I think it would be an interesting idea for a champion. The Rift Mechanic's passive would be to have each of his allies start with a vehicle (suited to which champ they are playing if Riot really wants to get crazy) that would have its own health bar and gas gauge that would run out over time (or by being damaged by enemies). The vehicle would then have to stay wherever it runs out of gas or breaks and The Rift Mechanic would have to come fill 'er up or fix the damage. Other abilities could include setting up a gas station or repair shop somewhere on the map, or creating an oil spill that would cause champions who pass over it to speed up. What do you guys think and what other "modifications" could you see for his kit?
