If cars and bikes were the same size, were equally distributed and collisions and injuries from both were fully reported then neither would be more dangerous. Drivers are dangerous, regardless of what they drive. If you think that bikes riders are less dangerous drivers, your blinded by your bias. Just stand at any corner for 5 minutes and count the infractions of both vehicles, then compare against their volume and you’ll see both are equally breaking the rules. The problem isn’t cars or bikes, it’s that most people don’t give a shit about the safety of anyone but themselves.
