回答题While car sharing is a concept that’s catching on，old—fashioned carpooling where a group of people take turns driving each other to work has always faced a resistance(抗拒)．In a study on traffic problems by ABC News，84％of those who drive to work say that they still do it alone．More than half of those lone riders insist that carpooling is just too inconvenient，and 18％say they simply don’t know anyone to share a ride with．
Now technology makes carpooling easier and more fun．NuRide，a company provided an on-line carpooling service last year，offers daily travelers in the Washington area not just a web—based list of would—be carpoolers but also a way to arrange a trip online．Here’s how it works：rider seek—ers enter the positions where their trip will begin and end，the time they want to leave and if they’re willing to drive or just ride in someone else’s car．The website’s search engine then looks for matches and makes lists of the names of traveling companions，along with the car model and the ex—act time and place to meet for each trip．People who want to share the ride can show their interest in joining in online and then meet their car mates when it’s time to 90．
NuRide users aren’t riding with total strangers．They are required to provide the name of their employer and a work e—mail address，both of which need to be checked before being listed on the
website．
To attract users，NuRide offers a frequent rider prize：anyone who shares a ride gets a$1 credit．So far，2，300 people have signed up．NuRide CEO Rick Steele said that more man 50．000 tides have been arranged on the website，resulting in 1．4 million fewer miles driven and 650 fewer tons of automobile emissions(机动车排放)．

B．Only l8％can find their road mates．
C．Some people consider it dangerous．
D．Half of the people accept the idea．
