Depending on your definition, this actually is not peak performance.

Subways are.

Obviously, the tunnels are absurdly expensive, but nothing moves as many people as quickly around a city as a subway.

They’re also extremely reliable, meaning people are even more likely to actually use them, and their above-ground footprint is essentially zero.

It’s the quiet part that’s (usually) not said aloud.

Just take a look at the statistics of how i.e. criminal law is applied much more aggressively to conservative out-groups (PoC, poor, etc.) than conservative in-groups (white, wealthy, etc.). Then have a look at who is proposing politics intended to fix that imbalance an who’s talking about “taking a hard(er) stance on crime”.

Another, rather specific example: https://www.dailymail.co.uk/femail/article-8769269/Former-abortion-clinic-worker-recalls-pro-life-women-justify-procedures.html

Once you look our for the pattern, you’ll see it everywhere.
