What's with all these young guys going full steam around traffic and ramming into cars? Thinking of Egan Bernal, Tom Pidcock a couple years ago, and now Remco. There is a time to go full steam and a time to be cautious. Maybe young guys just don't have a lot of wisdom.
In his defense, it looked a pretty run of the mill relatively empty (midday) belgian town center. The traffic was probably almost-non existant. It's just that it's a town center. So stuff like a car door opening and closing more likely to happen there than elsewhere.
And whilst I definitely don't want to put the blame on Remco; As just random bad stuff can just happen to anyone. And clearly that postal worker failed to check for incoming traffic before opening her door. But, odds are there was a speed limit of 30 km/h in that town center. Not sure exactly. But that tends to be the case in most town centers in Belgium these days. And odds are Remco was going faster than that. I daresay that even if colliding was unavoidable and would have hurt a lot regardless. Colliding at 30 km/h or at +50 km/h is different, as well as the pain and damage resulting from the crash. Again, I ain't blaming Remco. Pretty sure most (Pro )cyclists don't bother to abide by the speed limits when training/riding.
I mean close to where I live there is bike highway which has a speed limit of 30 km/h. Most people on there tend to go faster. Either with their electric bikes or racing bikes. Hell, even a slow turtle like myself whom enjoys riding their bike at a leisurely pace will probably go over that limit with a bit of helpful wind.
I guess i'm just agreeing with you in the end that maybe a little bit of prudence around certain traffic, certain places is better than taking any risks. Especially since even carefully riding your bike can be dangerous enough around certain cars. Not knocking all car drivers, just a certain group. Just as I would knock not all cyclists for certain behaviour. Just a certain group of cyclists who think they own the road and think it's okay to drive/ride agressively around other people.
