To put it most simply, whatever with four wheels can be defined as automobile. With living standard raised, there is still enormous potential for further development of automobile market in moderate cities. Widely automobiles are sure to be used as mobilephones, which, however, leads to some problems in environmental pollution, traffic safety and traffic condition.

Increasing number of automobiles is on the road, however, less is known that how great the heavy metal pollution has been caused every single additional action of start or brake. The latest survey by   Institute of Geographic Science and Natural Resources Research, CAS shows that heavy metal pollution caused by automobiles becomes far much worse and the way to prevent further pollution should be put premium on by all circles. So the selection of new material quality should be valued, such as something like silica gel can be applied for new manufacture of the automobile body, which benefits both pedestrians and bicycles for accidental harm could be reduced.

Hidden danger lies there when necessarily immediate reaction for accidents can’t be reached by drivers and it is always the case when high speed is attained. Nowadays, security measures, such as Air bag Supplemental Restraint System can only serve to reduce harm afterward. It can really work if driver can make the most efficient reaction in shortest time, much effective than SRS. An accident-telling device can be set on the automobile, according to traffic or driver’s action, informing possibility and degree of a potential accident in next second, to give drivers judgment and instructions so as to avoid or reduce accidents.

In the coming future, transport may become unpleasant due to heavy traffic jam caused by increasingly wide use of automobiles, when a burden automobile becomes. So, motorcycle or bicycle will become new favorites. It costs too much for automobile to become air vehicle, but a ship-shaped body and escort-abandoned design can not only reduce injury caused to escort in accident but also a spot in design.
