33.What would the world be like if cars could drive themselves?Imagine seeing an empty car passing by on its way to pick up its owner,or a car full of passengers who are reading,listening to music or even sleeping.But none of them are worried about the road ahead. Well,all of this could be the future of driving.There are several companies,including Google,working on driverless cars.So far,no Google self-driven cars have gotten a traffic ticket (罰單),but some of them have been in accidents when other cars hit them. These cars are now still in the testing stages (階段).But,if the tests are successful,these electric self-driven cars could be put into use very soon. The cars are so special that they can take the place of drivers during certain situations.They are able to park themselves,or slow down when they notice objects close by.They can also stop easily if there is danger. Scientists and engineers believe,with the help of wireless signals (無線信號(hào)) ,cameras and GPS,creating a safe self-driven car might be possible.The cause of deadly (致死的) road accidents is usually careless drivers or bad conditions.The self-driven car may be able to prevent(防止) these.However,some people don't like the idea.American lawyer Whit Drake does not believe these cars are safe.He thinks that technologies can also be mistakes.
