Your car will change even more than that in the next 10 years.One of the biggest changes is that cars will drive themselves. Some day you may not need to drive a car. You will just tell the car where you want to go and it will drive itself.“We definitely W1 have the technology for it now，” says Andrew Poliak of automotive technology supplier QNX. “We expectselfdriving cars to be a mainstream(主流) thing between 2020 and 2025.”The American company Google has been working on a selfdriving automobile for years. These cars are already on the roads in the United States, mainly in California. Google c ars are truly selfdriving. These cars have no steering wheels or pedals.Last week, police ordered one of Google's cars to stop for driving too slowly on a public road. The car was not disobeying W2 any law, so no one was punished W3. But police did speak with the operators W4 of the vehicle.According to Google, its selfdriving cars have been driven nearly 2 million kilometers. That is equal to P1 the distance the average person drives in 90 yea rs. So far, no Google selfdriving car has gotten a traffic ticket. Some of them have been in accidents when other cars hit them.Other companies are working on selfdriving cars. MercedesBenz. Audi, BMW, Volvo and Toyota all have plans far such vehicles.A company BestMile called plans to operate selfdriving buses in Switzerland next spring. The buses will hold up to P2 nine people and will be tested for two years. MercedesBenz is developing large selfdriving trucks for long trips. These trucks use drivers to control them.A company called Royal will have selfdriving trucks at construction W5 sites in Florida by the end of this year. No drivers are needed in these vehicles.篇章导读：本文为说明文。
