I mean like:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    printf("[debug] OnPlayerKeyStateChange(playerid = %d, newkeys = %d, oldkeys = %d)", playerid, newkeys, oldkeys);
    // rest of code
}

Then just look what it returns for newkeys when you press LSHIFT in vehicle.
