Difficulties in obtaining the right to drive a motorcycle may result already from the fact that he sat on a motorcycle we need to maintain balance. Not everyone is easy to achieve. On the basis of the fact that - from the need to maintain a balance, and ending with the fact that driving license for motorcyclists is difficult, because the instructor is not in the same vehicle, every student - we can say that getting a license for a motorcycle requires really a lot of effort. However, this does not discourage people who want to manage their own engine. It is true that, during the practical lessons in this category may appear to be much more problematic and dangerous events, but this challenge can be met through a systematic science.
Useful gadget for the car
Among the many highly advanced technological solutions can not fail to make life easier for drivers. A perfect example is the so-called parking sensor, which means that you can safely fit in the car, even in a small space. This gadget is not currently too expensive, and its value for the majority of drivers will be huge - definitely worth it to invest, as we move through the crowded city streets, and we have every day problems with the appropriate parking the car. This sensor, as well as many other facilities for drivers are becoming more popular, and above all, their price falls. This is certainly an argument for buying small appliances that make life easier on the road.
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
