text: In America, we use vehicles on a daily basis to get around.  You either drive a vehicle that you own, ride a bus, take a taxi, ride a bike, or walk.  It is rare to see someone walking or riding a bike these days, but that is because we are so dependant on motor vehicles.  If you take a look at other countries, you will realize that they are taking steps to cut back on the use of motor vehicles to help stop pollution.
