By allowing you to cover more ground in less time and giving you the strength to carry more, the Segway® PT will reduce our need for cars and other vehicles with combustion engines. We think this will produce some profound environmental changes—both in the long and short term. As you consider these statistics and scenarios, bear in mind that these examples cover only the U.S., whose automobiles consume about 15% of the world's oil. (In 1996, new car sales in Asia alone exceeded those of North America and Western Europe combined.)
Reduced fuel consumption
American drivers take approximately 900 million car trips per day. The EPA estimates that half of all those trips are less than five miles (8 km) long and transport only one passenger—trips perfectly suited to Segway PT. If these 450 million daily trips last an average of three miles (4.8 km), we can say that Americans drive 1.35 billion miles (2.16 billion km) per day on trips five miles or shorter. If the average automobile gets 21.5 mpg (9 km per liter) in the city, that's about 62 million gallons (235.6 million liters) of gas per day burned on trips where people could be traveling on Segway PT instead of driving. If just 10% of those trips were replaced, that's 6.2 million fewer gallons (23.56 million liters) consumed per day or 2.26 billion fewer gallons (8.59 billion liters) per year.
If the annual fuel consumption of U.S. automobiles was reduced by 2.26 billion gallons (8.59 billion liters), that would translate into a huge reduction in vehicle emissions. This includes 405 fewer tons (364.5 metric tons) of hydrocarbons, 61,830 fewer tons (55,647 metric tons) of CO2, 3,105 fewer tons (2,794 metric tons) of CO, and 6.2 million fewer gallons (23.56 million liters) of uncombusted gasoline. What's more, we believe this to be a conservative estimate, based on the fact that each 1% reduction in urban miles driven results in a 2% to 4% reduction in vehicle emissions, due to the inefficient nature of urban driving.
Reduced stress on the environment
If each car is driven 1,825 fewer miles (2,920 km) per year, that saves 9,125 miles (14,600 km) over five years, easily enough for that car to be driven for one additional year. If each car could be driven an additional year, that would put less stress on landfills and on the environment as a whole.
