Every day you share the street with other people who walk, use a wheelchair, ride a bike or drive a motorcycle, a car, a van, a truck, etc. There is a myriad of ways of moving from one point to another. I like to think it as a pyramid regarding the protection each group should have. On the bottom of this gradation, there would be walking people and wheelchair users since each and every person belongs to this group and are the most vulnerable. Next, bikers and skaters would take up the second step. They go faster than most of walkers. This fact determines they should ride in a different, separate space in the street in order to avoid accidents and troubles. Then, we have the motorcycle drivers. Obviously, the speed they reach is the higher up until now, but they are fragile compared with car drivers. It is no difficult to imagine who would be worse off in an accident between a motorcycle and a car. On the top of this pyramid I put car, van and truck drivers. Since they move in the heaviest machines, the potential damage they can cause in road accidents is the most important. Indeed, it is common that most of deaths in road (at least in Western countries) are car drivers.
