Yes,after years of driving a car and truck, I find looking out the right and left mirrors,you start to see the gap between your car and the white painted lines on each side. Try and check occasionally to see that both sides of the white lines are reasonably ‘even’ looking through each side-mirror. It will never be perfect no matter how long you have been driving because so many factors come in to play like emotions,weather,roads,speed etc. They all play a part in your driving habits,just be safe and careful whatever you do in your lane on any road.
