Even with cars we have a saying: "graves are filled with people who had the right of way". Physics doesn't care about whose to blame.

It's not about blame. It's about recognizing the need for safe infrastructure: physically separated bike paths, not painted gutters. Physics does care about the difference between crossing a painted line vs hitting a bollard.

And trying to pivot a conversation like that often gets... blank looks.

No need for people to find the info unknown or confusing.

“If it doesn’t damage the car, it’s not safe bike infrastructure.” someone said, and they’re right.

Dedicated bike lanes almost always share the same risks as the incident in the OP: the intersections are still shared. And sometimes driver behavior is even worse when dedicated bike lanes exist at intersections, because drivers turning right forget they are sharing the intersection with bikes proceeding straight-through from a lane on their right.

> factors that can be fixed

In the US? Not a chance. The political momentum in the US overwhelmingly does not want to fix this.

There's only one place in the US where you can reasonably ride a bicycle for transportation and (usually) not share the road with cars, and it's a tiny island with population ~500 that banned cars in the late 19th century. And even there, emergency vehicles, like the one in the OP, still share the road with bikes.
