Your implication is that cyclists who don’t want to be close-passed are wimps who shouldn’t be on the road. You used the term “safe space”, which is usually pejorative. My point is that those cyclists are braver than the drivers who wouldn’t be on the road without a protective, climate-controlled bubble (their vehicle).
It’s not cyclists who feel the need to bring a climate-controlled metal protection bubble onto the road with them.
Fear of other road users is in part what is fueling the SUV boom.
