Reasonable except for the helmet part. Anecdotal: I've gone through two smashed helmets. One due to taxi vs. cyclist and another when bicycle lowsided on wet leaves at a walking pace. Both times the helmet absorbed significant damage.

Helmets are a layer in defense. It's not a perfect shield and will not help in catastrophic situations. However in the more likely situation, the helmet does help.

Current cycling helmets are well ventilated and lightweight.

We should be providing information about the risks and rewards. It's up to the cyclist to decide how they want to proceed.

Me: 32km (20mi) each way, slicing through the Tokyo metro area.
