About this product
●The first function is emergency braking. If we need to brake urgently in an emergency, we can use the rearview mirror to observe the distance from the vehicle behind us. If it is too close, we may cause rear-end collision with the vehicle behind us if we brake sharply. So when we brake hard, we can look at the rearview mirror and observe the position of the vehicles behind us.
●The second function is to change lanes. When we are driving on the road, if we need to overtake or change lanes, we can use the rearview mirror in the car to observe the vehicles behind us, so that we can turn on the turn signal to change lanes or overtake after judging the distance to the vehicles behind us. That also ensures our own safety and the safety of other vehicles.
●The third function is to judge the distance between vehicles. We must keep a safe distance from the front and rear vehicles when driving on the road. It can also be well judged by the rearview mirror in the car. The rearview mirror is also used to judge the distance between vehicles when we brake sharply or change lanes, as we said earlier. The distance from the rearview mirror to the vehicle behind is relatively accurate.
