The problem in our society is that most people feel so entitled to their car that they are blinded and resistant to anything that make life for people safer and healthier. But that makes no sense. Most cars on the street carry one person, just like a cyclist or a pedestrian, but most of the energy cost is just to move the car, not the driver/passenger. Plus, cars require a huge amount of infrastructure at tax payer expense. Private motor vehicle use is the most subsidized form of transportation. More than transit, and definitely more than cycling or walking. Talk about an irrational society.
