今日のテキスト UNMANNED BUSES, TAXIS (are) PLANNED FOR 2020

The race is on to develop driverless vehicles, including buses and taxis. Japanese government officials say they are going to give the green light to public transport operators aiming to go driverless by the year 2020 ― that's the year Tokyo hosts the Olympic Games.　
The officials say operators will be obliged to take full responsibility in the event of accidents. The companies will need to have systems that monitor their unmanned vehicles remotely and stop them when problems arise. The officials plan to amend the Road Traffic Law and study other measures. They will also call on would-be operators to start test runs on roads in special zones designated by the government.
