What does "look at the front of the car for overtaking, and the rear of the car for passing" mean?

Hello everyone
This is the only official Black Panther TH-cam channel, others are pirated
is a car enthusiast
Share car knowledge every day, don’t miss it. The earth will not explode, and the black panther says that the car will not be on holiday
Independent point of view, objective explanation, actual measurement interpretation, objective evaluation, just look good but not popular
Thank you for your love
