This image would suggest you're incorrect. "almost always" made me laugh though
Do you think having 6 year olds biking in the middle of traffic is acceptable, just to placate drivers? And it's 100 meters and then it's a new car. And another one. All the time.
And then the adult can use their bike to take the lane, stopping traffic, and let the 6 year old go around.
No need for loud horns or confronting people.
Saying "kindly" doesn't not make this incredibly rude. Much like parking in the bike lane, lecturing a stranger, or sounding a loud horn in a crowded area.
By all means, take a pic, file a request, get the drivers ticketed. But then also go around. Please don't sound loud horns or confront people - it's rude and a bad idea.
