OnPlayerEnterVehicle is called when a player is preparing to enter a vehicle, so for example: when a player hits the 'F' key near-by a car.

You can use OnPlayerStateChange, this might be a more appropriate callback if you're forcing a player in to a car, or if you want it to call when they directly enter the vehicle instead of before.

public OnPlayerStateChange(playerid, newstate, oldstate) {

        /* your code here */
        return 0;
