Huh? You are claiming Tokyo is shit, so is there a city of conparable size that does better? Or are you just demanding something impossible?
This is a political problem and as long as the Japanese auto lobby has the LDP in their pocket, we who live here live the consequences.
IMO, what other cities do (and the results they get) is relevant when discussing what’s good, bad, or practically possible.
Where’s the inconsistency?
The comment you responded to was about how this low noise experience is not unique to Europe, and saying Japan has similar experiences.
You came in with "Tokyo has shit air" as a response. Now you claim the others are "whataboutists" when they are merely continuing the original conversation topic comparing Europe with Japan.
