Ambulance and transit are both very different arguments from a single car.
Both the bikes and the car are supposed to make room for the ambulance.
Regulation about right of way for buses probably changes a lot between jurisdictions, so I don’t really have anything to say about that.
Not at all if the argument is size alone or just spouting emissions. It’s a dumb cartoon to pair with the title.
If the argument is size alone then there’s no concept of transit or ambulance or priorities.
It’s ridiculous to try to make a case against bikes by bringing up an imaginary emergency, but then taking that scenario away.
It’s simple. Replace that car with a fire truck. The cyclists look like the biggest asshole regardless of size of vehicle.
