1. Motorbikes are a wee bit faster and heavier than bicycles. With this comes more danger.
2. Motorbikers are not the most vulnerable road users.
3. Motorbikes often have a lockable container to put the helmet.
4. Don't you dare to call my arguments "stupid" - I've won way too many arguments regarding this very topic to know they are NOT. Calling them out as "stupid" without any specifics: that's blatantly lazy however. And not the kind of "discussion" I tend to engage in.
