This is a genuine question. We don’t have the wide angle view on this pic so I can’t tell if this road is part of a wider bike-only network of roads in the city center, a bike-only turn-off from a bigger shared road that car drivers are expected to know not to turn down into, or a shared car/bicycle road.

the no-parking sign is for bikes

Lol.

the paint is clearly intended for bikes here

I’m talking about the painted arrow partially hidden behind the striped shirt guy. Looks like an arrow for cars to me, with the bike box and bike arrows painted in front of it.

Why would you need bollards?

My city has a wonderful grade-separated bike path between a river and a major road. The car drivers at various intersections repeatedly kept taking the turn wrong and driving down this “clearly” bike path, repeatedly killing bicyclists, because the city was refusing to install bollards for some reason. They were saying the “no cars” signs were sufficient. The city only put concrete blocks there after a literal terrorist took a joyride in a van down the bike path for miles, killing dozens.
