Have you ever heard of the cars without drivers?Don't be too surprised if you see a car like this going down the road in Beijing these days.It might be one of Baidu company's driverless cars.Last month,Baidu company began to test its driverless cars on open roads in Beijing.Let's learn something about the driverless cars. Driverless cars began to be developed in 2010.Since then,companies like Tesla,Uber and Baidu have been working to produce and test their own driverless cars. Driverless cars are safer than common cars.And they are more environmental-friendly than common cars.They are more convenient and allow disabled or blind people to get around more easily. But driverless cars have their own problems as well.In one test,researchers pointed a laser pointer at the car's sensors(傳感器) while it was moving.The car mistakenly thought that the laser beam(激光束) was in its way and slowed down or changed its direction. The software(軟件) that is used to direct the cars may not be perfect enough.That's because sometimes it may break down.When we use our computers or smart phones,they sometimes don't work without any reason.And if this happened while driving,the results could be terrible.Improving the software could be the best way to deal with this problem. |
