The magical means of transportation in the future - smart cars

Smart cars are expected to be parked in your garage as early as 2020, and by 2030, maglev trains will be able to help you travel across continents in 2 hours or less. This is the latest prediction of American scientists. Pelletier, a famous American popular science writer, said that we can imagine a 370-kilometer trip from Las Vegas to Los Angeles in a smart car in the future. You jump in the car and tell it your destination. The car will then operate through the automatic highway system, and the sensors will guide you very safely, driving at speeds of up to 225 kilometers per hour. You sit in the driver's seat and the car drives automatically. You can read the newspaper, surf the Internet, watch TV, or take a nap. After 1 hour and 40 minutes, you will arrive at your destination relaxed and ready to have fun. The necessary technologies to build such a car are now relatively mature. There are still two steps to go before the advent of smart cars: one is to make computers truly able to drive the car automatically, and the other is to develop an automatic highway system. Both technologies are currently being tested on Interstate 5 near San Diego, USA. Smart cars can reach speeds of up to 225 kilometers per hour and can be protected by shock-absorbing radar. Smart car technology can safely drive three times the normal number of cars on the road. This high-speed, high-performance driving technology will relieve the pressure of traffic jams, reduce pollution, reduce the need for additional roads, and save lives while eliminating accidents. By 2015, the first generation of smart cars will be able to avoid collisions. By 2020, the second generation of voice-recognizing cars will be able to drive themselves on automated highways. By 2025, the third generation of smart cars will receive instructions from muscle nerve impulses, eye movements, and brain waves.
