课时作业(二)

It's a late night in the Metro area of Phoenix.Arizona.Under the streetlights.a car can be seen
slowly approaching and parking.A green and blue“W”glows(发光)from the windscreen,giving
off just enough light to see inside-showing a completely empty driver seat.When the person
waiting for it opens the door to climb inside,a voice greets him."Good evening.this car is yours,"
it says.This is a Waymo One robotaxi,ordered just 10 minutes ago using an app.
The promise of driverless technology has long been inviting.It has the potential to improve our
experience of commuting (and long journeys and take people out of high-risk working
environments.It's key to helping us build the cities of the future,lowering carbon emissions.And it
could make traveling safer.“We want safer roads and less accidents.Automation(自a动化)could
provide that,"says Camilla Fowler,head of automated transport for the UK's Transport Research
Laboratory (TRL).
But in order for driverless technology to become mainstream,much still needs to change.
Driverless vehicles should be a very calm way of getting from A to B.But not every human
driver around it will be driving in that way,"says David Hynd,from TRL."It's got to be able to
deal with human drivers speeding.for instance.or breaking the rules of the road."
And that's not the only challenge.There's regulation,rethinking the highway code,public
perception,improving the infrastructure(基a础设施)of our streets,towns,cities,and the big
question of ultimate responsibility for road accidents."The whole insurance industry is looking into
how they're going to deal with that change from a person being responsible and in charge to the
vehicle doing that,"says Richard Jinks,vice president of commercial at Oxfordshire-based
driverless vehicle software company Oxbotica,which has been testing its technology in cars and
delivery vehicles at several locations across the UK and Europe.
