> As vehicles, they have to stop at stop signs and lights, but feel like quite an appreciable percentage do not. I guess that this is a problem of how energy conservation works. When a cyclists stops they lose all their gained energy, like any other vehicle. But then, the cyclist needs to put a lot of effort to get again to their original speed. If that stop is in front of a slop the cyclist only option is to get off the bike and walk. So, maybe it is more a fault on the design of the roads than on the cyclists.
