Alcohol and driving is
Driving after drinking can be dangerous even when guided bike. In the case of more complex machines, allowing to achieve a much higher speed, directing them under the influence of alcohol can be fatal. Despite the many social campaigns regarding the prohibition of driving under the influence of alcohol and strengthen penalties for drunk drivers, unfortunately, many of them still do not apply to this rule. Meanwhile, the management of a car under the influence of alcohol can lead to death of not only the driver and passengers, but also to the disappearance of completely innocent people, not even staying on the road during this event. Getting into the car under the influence of alcohol we create unnecessary risk.
Kind principles on the road
Novice drivers often have no idea how to navigate especially in large cities. Skills acquired during the course of a driving license are often insufficient to freely continue driving after passing the exam. But do not scare initial failures in this respect - nobody immediately not yet led to any vehicle like a professional driver, and each kilometer is a valuable experience. It is worth noting that many motorists used polite rules on driving. A valuable signal to a driver who, for example, let us in on a congested intersection is sending him a thank you for using your own lights. Such light signals can be very useful when driving culture.
Fuel and propulsion technologies
Most cars in use today are propelled by an internal combustion engine, fueled by deflagration of gasoline or diesel. Both fuels are known to cause air pollution and are also blamed for contributing to climate change and global warming.4 Rapidly increasing oil prices, concerns about oil dependence, tightening environmental laws and restrictions on greenhouse gas emissions are propelling work on alternative power systems for cars. Efforts to improve or replace existing technologies include the development of hybrid vehicles, plug-in electric vehicles and hydrogen vehicles. Vehicles using alternative fuels such as ethanol flexible-fuel vehicles and natural gas vehicles are also gaining popularity in some countries. Cars for racing or speed records have sometimes employed jet or rocket engines, but these are impractical for common use.
Oil consumption in the twentieth and twenty-first centuries has been abundantly pushed by car growth; the 1985?2003 oil glut even fuelled the sales of low-economy vehicles in OECD countries. The BRIC countries are adding to this consumption; in December 2009 China was briefly the largest car market.35
