It's because you are checking if the player is near some coordination.

Check with this.

pawn Код:

IsPlayerInAnyVehicle(playerid) && GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
{
     GetVehicleVelocity(GetPlayerVehicleID(playerid), x, y, z);
     SetVehicleVelocity(GetPlayerVehicleID(playerid), x * 6, y * 6, z * 6);
}

Also,m you want to speed up the vehicle as soon he reaches a position?
Or you want to speed up the vehicle when he teleports?
