I was sitting at a stop sign, in a lane that has sharrows. Waiting for a car to go by I feel a push from behind and get almost pushed into the car I'm waiting for (my hands aren't on the breaks, by feet are on the ground). Adrenaline skyrockets, I look back see this guy not really concerned, I look down at my bike, then back up at him, and just say "Dude, what the fuck?" (not really yelling, trying to stay calm). The guy's response "Chill out, it was an accident." Of course at this point I flip out.
To be honest, this is one of the better experiences I've had when cars almost seriously injure me.[0] There is a frequent challenge of avoiding doors being opened on you while also not pissing off the car following you in the sharrow road. Of getting out of intersections as fast as possible (because getting hit at a stop sign is pretty common). Avoiding pedestrians that step right off the curb into you. I ride without headphones because I have to be aware.
I have found that riding in protected bike lanes, a lot of this decreases. There is extra space for me at stop signs/lights, drivers have to stop sooner. Cars are parking out, and are more likely to look before they open their door. Pedestrians notice something is off and actually look both ways before stepping off the curb. I think the green painting helps too. Honestly I feel A LOT safer in a protected bike lane.
[0] worst experience is that this guy cut me off, almost hitting me, I flipped him off and he proceeded to try to hit me with his car. As in he got behind me and came over into the bike lane. I bailed into the sidewalk and he hit the curb, then he drives off.
