there aren't many times I've seen anyone start a car with something like this..

I've seen dragsters started with a portable starter attached with welding cables to batteries, which prevents that dragster from having to have a starter on it, and the wiring, starter relay, etc. 

I've seen drag strips with roller starters, I've seen dragsters push started, and I've even started a a car with a dead battery by getting it rolling and popping the clutch, and I've seen tractors started with the ol hand crank... but I haven't seen a rig like this in action until now
