Wonderful accident 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 a rear-end collision. So old drivers generally don't hang this.

As long as you always look in the rearview mirror, if the other person is too close to you, you can lightly step on the brakes, which is not a real brake. Just let the brake lights light up frequently to remind each other to keep their distance.

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