Automobile anti-collision slogan

In fact, there is no need to hang these things, and it is of little use. On the contrary, the car behind you is easily distracted when reading your clever tips, which is more likely to cause rear-end collision. So old drivers generally don't hang this.

As long as you keep looking in the rearview mirror, if the other person is too close to you, you can lightly brake, not really brake. Just let the brake lights light up frequently to remind each other to keep their distance.

If this reminder doesn't work, keep a large distance from the car in front, so that you can slow down when braking, and give the car behind you more room to react, and then change lanes if necessary. You can hide if you can't be taunted.
