One gets accused of being an inbred redneck as they "roll coal" at the other one, while the other one sneers at regular people. They're both bags of rancid dicks for very different reasons.
I don't know about where you live. But here cyclists stick to the cycling paths almost all the time. A simple chime or ring from their bell will do just fine to let people know if they're coming. No need for sneering buddy. Let go of your anger.
Regular people meaning people who know someone else using a bicycle doesn't harm them in any way therefore they don't care. The truck guy and the bike guy however won't stfu about it.
