Sitting among a sea of cars, have you ever dreamed about your car taking off and flying over the road? Many of us spend an hour or so stuck in traffic every week. The main problem is that we are not expanding (扩展)our transportation systems fast enough to meet ever increasing demands (需求). One solution is to create a new type of transportation that doesn't rely on roads.
In the last century, planes and cars changed the way we lived. Cars, which can be afforded by the general population，have allowed us to move farther. Planes have also cut travel time to faraway destinations(目的地).At the beginning of a new century, we may see the realization of a century-old dream一the mix of cars and planes or flying cars.
You might have heard news about flying cars before. The technology to make them safe and easy to fly may finally be here. With progress in lightweight material，computer models and no-man control, the dream is very close to becoming real.
Car maker Moller went public with the Skycar M400 in 2011. It is the first car that can take off and land straightly. The four-seat Skycar is powered by eight engines(引擎). The cost of a car is about $1 million at first, but when it begins to be produced in large amounts, that price could come down to as low as $60,000.
The latest flying car City Hawk is predicted to be tested between 2021 and 2022.It is similar to the Skycar except for its power source. The important difference lies in the power fans that seem much quieter on the road. The City Hawk is about as large as a middle-sized car. It could be used as an air taxi for news collection and traffic control.
The popularity of flying cars could be very exciting or very scary, depending on how you look at it. If proper rules are put in place, they could be the answer to our ever-heavier traffic pressure.
