how do I make the lines go under the car and get removed after a period of time?Thanks ahead of time.

Maybe you should add a line like this in your act method: 
time--;
By the way, the following way is more efficient I think: 
private int time = 100;

protected void addedToWorld(World w)
{
    turnTowards(getWorld().getObjects(PlayerCar.class).get(0)).getX(),getWorld().getObjects(PlayerCar.class).get(0)).getY());
}

public void act()
{
    time--;
    if (time<0) getWorld().remove(this);
}
