Automotive sunroofs are generally not completely sealed / waterproof. The leaked water just flowed away from the diversion tank. Blocking the diversion trough may cause water to flow into the car. So there will be old drivers who choose cars without sunroofs.
Chinese law does not mandate the installation of front fog lights. This has led many manufacturers to save the province, the front fog lights look at conscience!
Xenon headlights have the effect of dust collection. Many countries have forced xenon lamps to be equipped with cleaners. (Regulations require a cleaning device for lamps with a luminous flux greater than 2000lm, not all xenon lamps need to be installed.)
It is not mandatory to turn on the turn signal when entering the roundabout. Turning out of the roundabout requires turn signals.
The intersections without traffic lights follow the principle of giving right. Only for vehicles traveling straight, the description of the specific situation is complex, see subject 1 for details.
At the intersection without traffic lights, if you encounter opposite turning and conflict, turn right to give way to left.

Passing intersections without street lights at night, replacing the whistle with a switch of far and near light can remind vehicles at the intersection more effectively.
In previous years, the refueling speed of the F1 refueling gun was 12L / S, which required three people to support.
The wind resistance coefficient of automobiles is generally smaller than the wind resistance coefficient of human body walking upright.
The role of the front and rear anti-collision steel beams is to absorb energy during low-speed collisions, thereby reducing the degree of damage to the body steel beams. The protection provided by high-speed collisions is very limited.
There are original fire extinguishers under the front seats of Mercedes-Benz and emergency kits near emergency tools.

At 80km / h cruise, 60% of fuel consumption should be used to overcome wind resistance; if you can drive up to 200km / h, the air resistance accounts for 85% of all the resistance of the car. This is an approximation. It varies greatly from vehicle to vehicle.
The "pearl lacquer" used by some brand models is really doped with pearl powder, and more solutions are coated with metallic titanium and iron oxide on mica.
The world's first car seat designed for child safety was introduced by Volvo in 1967.
