Make a car, set 4 actors near the car with "Enter in the nearest car" animation, set them like this:
- Actor 1 - Spawn him near the driver seat, choose "Enter in the nearest car - Driver seat", choose a driving behaviour, set the route point
- Actor 2 - Spawn him near the front passenger seat, choose "Enter in the nearest car - Front Passenger"
- Actor 3 - Spawn him near the rear left passenger seat, choose "Enter in the nearest car - Rear Left Passenger"
- Actor 4 - Spawn him near the rear right passenger seat, choose "Enter in the nearest car - Rear Right Passenger"
However, if you want the actors to sit in the car without doing the enter nearest car animation, choose "Sit in nearest car". That way, the actors will suddenly sit in the car
