To do this you must be the driver, and have power windows and window locks. Roll up all of the windows and lock them. Fart as much as you possibly can then turn the heat on and put it on recircle not fresh. You now have a dutch convection oven.

Five people are in the car and you are driving. Driver Rolls up windows turns heat on recircle and yells, DUTCH CONVECTION OVEN!
