题目内容
20．Terrafugia is the most known flying car that has awaited the world for its creation and user ability（可用性）．Passing on the new concept and making it possible made a lot of difficulties for the company．Its unique creation with the concept of its acceptable behaviour on road was a big challenge to meet．Even after the successful prototype（原型）production of the transition car，it was wondered whether it would be allowed on the local roads or not．Facing the big challenge，Terrafugia made efforts to pass its newly born plan on the roads from National Highway Traffic Safety Administration （NHTSA） and Federal Administration Aviation （FAA）．Keeping the safety of road and other users as primary concern，the authorities allowed the Terrafugia to land their creations on road．Still after the approval the compamy had to face various challenges to make this idea come true in real sense．
A major issue was the use of lighter plastic windscreens，as in normal cars the windscreens are of glass whereas in planes light weight polycarbonate（聚碳酸酯）wind shields are used to make the plane light in weight and give it a bird like effect to fly or glide．More over the transition tyres are used to handle the impacts of landing，so there needed to be a special allowance since there came a conflict between the tyres used for the plane and those for the conventional vehicles on the road．So the FAA allowed the company with a permission of 110pounds loading on the road．
The company seems to face a huge challenge in covering all aspects and making it a safe and comfortable ride with the minimum cost to the comsumers．Taking in account all there aspects，Terrafugia has delayed its final production and delivery to the customers till this year．
So if you are waiting for it to come out to the market and have a chance to check how you actually feel like sitting in it，you will have to wait a couple of more months!
