Yes, but humans being humans, this isn't the case and isn't going to be. Let's deal with reality, not reductionist fantasy.

If we take death of out of the equation we all live forever. It isn't a useful "if".

I never said that it was ever going to be perfect. I did say one could minimize the risk by following the rules and practicing defensive driving. Crashes aren't as inevitable as people make them out to be. I've avoided crashes while cycling as well as motoring by paying attention to the situation ahead and behind and proactively taking action to avoid putting myself in a situation where I would have crashed into another vehicle or been hit (e.g., seeing that drive not stopping for the red light and not driving into their path).

Separated bike infrastructure empirically reduces cyclist fatalities. And it isn’t hard to guess why.

The vast majority of collisions cyclists are involved in happen at intersections (incluing mid block drivways and alleys). Very few collision involve hit from behind.

Cycling infrastructure that places cyclists in the pedestrian position when crossing an intersection exacerbates the risk of getting into a collision when crossing the intersection because motorists aren't really looking to see someone moving at cyclist speed as they're exiting the intersection. The other problem is that cyclists are hidden from view by parked cars until a short time before entering the intersection. This makes it difficult for both the cyclist and motorist to see each other until it's too late to avoid a collision. If you're not riding where motorists are looking, you're far more likely to end up in a collision, fatal or not[1]

Breaking: Helmets and safety gear are largely irrelevant if collisions don't occur.

(Hey, PPE is also largely irrelevant if you are never in a situation where a virus can establish a foothold on your person!)
