alt Hacker NewsNo. Going around a parked car is a basic ability you need to have as a cyclist.
If you can't do that safely, then you have no business riding in the first place.
Looking behind you is not optional, as you seem to suggest it is. And if it is actually a "small risk", then you are going way too fast.
Again -- if you don't have the environmental awareness to go around a parked car, then you shouldn't be riding a bicycle in the first place. Full stop.
This comment assumes a high mix of cars and bikes in an environment of unseparated traffic.
With literal decades of near daily bike riding behind me I've rarely had to maneuver a bike or a car around a parked car in regular (not US) traffic flow.
