2．I was desperately nervous about becoming car-free．But eight months ago our car was hit by a passing vehicle and it was destroyed．No problem，I thought：we'll buy another．But the insurance payout didn't even begin to cover the costs of buying a new car-I worked out that，with the loan，we'd need plus petrol，insurance，parking permits and tax，we would make a payment as much as£600a month．
And that's when I had my fancy idea．Why not just give up having a car at all？I live in London．We have a railway station behind our house，a tube station 10minutes'walk away，and a bus stop at the end of the street．A new car club had just opened in our area，and one of its shiny little red Peugeots was parked nearby．If any family in Britain could live without a car，I reasoned，then surely we were that family．
But my new car-free idea，sadly，wasn't shared by my family．My teenage daughters were horrified．What would their friends think about our family being"too poor to afford a car"？（I wasn't that bothered what they thought，and I suggested the girls should take the same approach．）
My friends，too，were astonished at our plan．What would happen if someone got seriously ill overnight and needed to go to hospital？（an ambulance） How would the children get to and from their many events？（buses and trains） People smiled as though this was another of my mad ideas，before saying they were sure I'd soon realize that a car was a necessity．
Eight months on，I wonder whether we'll ever own a car again．The idea that you"have to"own a car，especially if you live in a city，is all in the mind．I live-and many other citizens do too-in a place that has never been better served by public transport，and yet car ownership has never been higher．We worry about rising car costs，but we'd be better off asking something much more basic：do I really need a car？Certainly the answer is no，and I'm a lot richer because I dared to ask the question．

A．most families chose to go car-free

D．Leave it alone．

For now，the taxis only ran in a 2.5-squart-mile  business and residential（住宅的）district called"one-north"，and  pick-ups and drop-offs are limited to specified locations．Riders must have an invitation   from nyTonomy to use the servicer．The company says dozens have signed up for the launch．and it plans to expand that list to thousands of people within a few months．
The cars-modified Renault Zoe and Mitsubishi i-MiEV electrics-have a driver in front who is prepared to take hack the wheel and a researcher in back who watches the cars computers．Each car is fitted with six sets of Lidar-a detection system that uses lasers to operate like radar-including one that constantly spins on the roof，There are also two cameras on the dashboard to scan for obsiiicles （障碍） and detect changes in traffic lights．
NuTonomy was formed in 2013．Earlier this year，the company was the first to win approval from Singapore's government to test self-driving cars in one-north．NgTonomy announced   a rearch partnership with Singa pore's Land Transport Authority earlier this month．
