I was on my bicycle one time, on a road that was plenty wide enough for a car to pass me with the required minimum space of four feet while staying in their lane. A car passed me going way farther to the left of me than they needed to, forcing a van that was coming in the opposite direction to pull over to the curb and stop. As he passed me, the van driver stuck himself halfway out his window and started yelling at me "you're gonna get somebody killed!" Asshole, go yell at the driver of the other car, I didn't do shit. And all that happened is it took you an extra five seconds to get to the red light.
Where I live, 99.9% of drivers are cool and give cyclists plenty of room. But that 0.1% means I'm probably risking my life every time I go for a ride.
