Sure, all other factors being equal, it would be less severe with everyone on bikes, but your initial post read rather dismissively to me. Rather than, “Well at least it wasn’t a car and they didn’t die,” it came across to me like “Nobody was in a car and it was unlikely to kill them, so it’s not a problem.” Perhaps that wasn’t your intent, but it’s certainly how I interpreted it. We can advocate for a safer mode of transit while also calling out dangerous behavior by people using our preferred mode.
