If you’re playing on a PC, there are two ways to switch seats in your vehicle. The first way is to use the arrow keys on your keyboard. The second way is to use the mouse. To switch seats using the arrow keys, press W to move forwards, S to move backwards, A to move left, and D to move right. To switch seats using the mouse, hold down the left mouse button and drag your character to the seat that you want him or her to sit in.
