The automobile industry will still rank as the most profitable and powerful industry of the twenty – first century. There were presently one billion cars on earth in 2010, or about one car for every seven people sales of the automobile industry stand at about a trillion dollars, making it the world’s biggest manufacturing industry.
The car, and the roads it travels on, will be revolutionized in the twenty-first century. The key to tomorrow 's “smart cars” will be sensors. “ We'll see vehicles and roads that see and hear and f eel and smell and talk and act,” predicts Bill Spreitzer, technical director of General Motors Corporation's ITS program, which is designing the smart car and road of the future.
Approximately 40,000 people are killed each year in the United States in traffic accidents. The number of people that are killed or badly injured in car accidents is so vast that we don't even bother to mention them in the newspapers anymore. Fully half of these fatalities come from drunk drivers, and many others from carelessness.
A smart car could eliminate most of these car accidents. It can sense if a driver is drunk via electronic sensors that can pick up alcohol vapor in the air, and refuse to start up the engine. The car could also alert the police and provide its precise location if it is stolen. Smart cars have already been built which can monitor one's driving and the driving conditions nearby. Small radars hidden in the bumpers can scan for nearby cars. Should you make a serious driving mistake (e.g., change lanes when there is a car in your "blind spot") the computer would sound an immediate warning.
By 2020, as the price of microchips drops to below a penny a piece telemetric ( 远程信息技术 ) could be adopted in thousands of miles of highways in the United States. This could prove to be an environmental benefit as well, saving fuel, reducing traffic jams, dec reasing air pollution, and serv ing as an alternative to highway expansion.
