Imagine if you could just flip a switch and unshackle yourself from the asphalt.
Traffic jams are the bane of any commuter.
Those of us who live in one of the 68 largest urban areas in the United States can expect to spend about 50 hours stuck in traffic this year. How airplanes work How horsepower works How a car engine works How a GPS receiver works The growing population is partly to blame for our congested roads, but the main problem is that we are not expanding our transportation systems. Another solution is to create a new type of transportation that doesn't rely on roads, which could one day make traffic jams a 20th century relic. To do this, we must look to the sky. Cars, which became affordable for the general population, have allowed us to move farther away from cities, and planes have cut travel time to faraway destinations considerably.
