What's missing from our roadways is called "courteous driving." It is likely compounded by ignorance and/or disregard for traffic laws.
Does the bike have as much right to use a public road as a car or semi? Yep.
Regardless of your type of vehicle, is it courteous to ignore every opportuniy to move aside and let others pass when you are incapable/too scared to go the speed limit or prevailing traffic speed? Nope.
Is it legal or courteous to tailgait, honk, pass unsafely, intimidate, or send obscene gestures to others on the road just because you're impatient? Is it anyone else's fault YOU are late for YOUR appointments? Nope.
If someone engages in rude/unsafe behavior around you but doesn't cause any physical damage to you or your vehicle, is it justifiable to "go after them" for revenge? Nope.
Are you the center of the universe when you're in front of other vehicles? Nope.
Are you the center of the universe when you are behind other vehicles? Nope.
Knowing/obeying traffic laws and courteous driving are key factors in road safety.
