You simply spin your wheels with L2/LT and while doing that then you get get out of your car and it'll still be on.
Just for clarities sake does this mean you input 3 things.
1 Turn your wheels with the Left analog in either direction
2 press and hold Left trigger
3 hold down the left bumper (L2) ?
Do i understand that correct?
great tip, another thing ive noticed, on GTA IV, you could leave the door open on a car when you got out, now it seems you cant.
hahahahahaha who really gives a f*ck, and you wouldnt do that in real life so of course they took it out
Actually you would do it in real life if you want to stay in the general area yet continue to use the music. Also you can illuminate dark areas with car headlights by pointing them in the direction you are walking.
One reason people might not do this in real life is because they own the car in question and the systems that produce energy inside them. GTA cars have no battery life or gas so it's irrational to be concerned about depletion of energy here.
