There are limits as to how large highways and freeways can be build. With increasing population, this means that cars would have to be smaller and more fuel efficient.
Global Traffic Congestion
However, bicycles use mostly only human fuels and give great cardio exercises. If cars are going to become smaller, then bicycles for single to 4riders can be just as great in certain circumstances.
Why don't we start the trend now? 2020 is only a relatively short while away. Should we persuade the federal government into reserving one protected highway/freeway lane throughout the country (each direction) only for bicycles?
This will serve 2 purposes:
1. Make people realize that highways/freeways would no longer (and can no longer)be expanded in width. This would explode the number of cyclists.
2. It would be a great alternative to secluded Bicycle Paths.
