Common cycling fallacies include the complaint: “Our roads are too narrow to build cycle lanes on.”
The site answers:
It is true that some roads may be too narrow to accommodate cycling infrastructure, alongside other uses like parking and multiple lanes for motor traffic.
However, it may well be the case that cycling infrastructure is a more beneficial and productive use of road space than parking bays on both sides of the road, or multiple lanes of motor traffic. A road can be made one-way for motor traffic, for instance, or one of two rows of parking on both sides of a road could be changed.
