Well, the car is a CUA which you can animate with timeline. Add it as a target in timeline (on the male or female to keep it simple) and animate its rotation along the movement of the characters.
This probably will look like sh*t because the Car won't have working dampers like a real one does -> changing the rotation of the CUA will make it clip through the ground plane. Maybe you can still make it work roughly by elevating the car a bit above the ground (make it float) and keep the rotation changes subtle. It probably still will look very weird due to the wheels moving together with the car. To solve that, the wheels need to be separated from the car CUA.
