I'd be interested if any martial arts have been adapted to cars... defensive driving, strategies, etc.. Its a big large, but its still a tool!
I have done joint locks in cars to keep people under control.
A person behind me after seeing twister and being afraid of tornado's grabbed the seat belt and my neck and started yelling twister. I turned the car towards a low point off the express way it also just happened to a small pond. After we left the road at 60 MPH, I slowed down that much, the guy let go of me more afraid of crashing into the pond as he could not swim. The mythical twister did not exist, but as soon as he let go of choking me, I grabbed his wrist and torqued him real bad while he was screaming what are you doing? I stopped the vehilce and told him and the other passengers you never choke or screw around with the driver accidents happen that way (* was a first responder to a car load of high school kids who died this way *). I explained that if there was a twister I could not see I had to trust him and his screaming to take action. I explained to him that I cared not if he could swim or not if he choked me again while driving, I would take him for a long swim. Him and the other engineers thought I took it a little far, but they never screwed around again while I was in the car or driving.
As to training with cars, get an old beater, and learn to roll across the front of the hood. This gets you into thinking about how to roll across a vehicle to get to safety.
There is no way to safely practice with a roll across a moving vehicle. Been there and done that, it hurts and had a limp for weeks. But I did not get "hit" by the car.
Another case, I was driving a friend home and we pulled up on two vehicles at a light, they were following each other so I could have gone to either side. Instead I staid back and coasted up slowly, two guys got out of the van following the car. I put the car in reverse and started going backwards, the friend in the car was concerned that I was now reversing the wrong way on a one way street. The guys were carrying something in their hands, and it looked to me like a scene out of a movie. It turned out that the objects were not guns and they handed them to the car in front of them. The friend was then really surprised about observation and reactions, even though he was a black belt before me, this had never crossed his mind.
There are lots of things a vehicle can assist with or be used to assist with your training.
