Let me tell you a story that has been repeating from the past century. We have a street and car stuck occurs often. Suddenly, one visionary says “Eh, we must improve the number of car lines so that cars won’t be in stuck anymore”. And then the street passes from two car lines to four ones at the expense of space for pedestrian. As a result, the number of cars also increases and car stuck comes in a few days. In this case the problem is even greater because space for pedestrian has been reduced and the more cars, the more pollution and noise.
One common argument of those who are blind to the improvement in sustainability produced by bikes lines, is to say that car lines reduction would be make everybody worse off. Note that the everybody in italic means “only themselves”. As the story I have explained earlier indicates, improvement in car infrastructure only causes more cars on streets. On the other hand, making bike lines on roads (and then reducing at least one car line) makes citizens better off as air quality improves and noises reduce. Moreover, as bikes take up less space as cars do, it is common that pedestrian space increases as bike line is built.
When car lines are reduced, dimwit car drivers blame against bike infrastructure instead of changing the car for the bike, the public transport or just walking. Replacing a habit by another is costing but if only they be open-minded enough to realize that everybody (now meaning each and every person) get better and improve their health.
