Additionally, cars are very dangerous for our community. Careless drivers put themselves and others in danger. Cars are critical to walkers especially to children if the driver is not looking at the road or is somehow distracted. Have you known someone whose toes or feet have been run over by cars while crossing the street?
Lastly, cars create social problems, which could lead to poor health. A few drivers suffer Road Rage and put themselves, loved ones and others in a threatening situation. Some cars create disturbing noises, and disturb people living near highways, freeways, etc. as they do not get enough sleep. People depend on their cars so much they forget to exercise their bodies and end up being obese or having heart problem.
As a result of the excessive number of cars on our roads, everyones life is in danger. In order to create an environmentally friendly and safe world, it is necessary for each country to limit the permits in number to control regional air pollution. Secondly, car manufacturers should try to improve the efficiency of vehicles, such as finding solutions to emissions of combustion engines, developing new power sources such as new fuels like natural gas. Thirdly, try to improve efficiency of traffic by setting up dedicated bus lanes and giving priority to car-pools and vehicles with 3 or more persons. Besides, traffic can be scheduled; for example, commercial traffic at night; large companies can shift working hours and decentralize administrative operations.
