Is that really true? The only people who need/want to regularly travel across local transit boundaries are tech people? That seems unlikely, especially nowadays.
I'm not trying to self-aggrandize here, but I'm bad at emails and good at code. I'm sure you can find a portion of HN users that fit the description but I don't think "people like us - the E-Mail caste" is the way to say it.
(This includes mails, but also code or marketing etc. - eg people that didn’t have the slightest inconvenience during lockdowns compared to „essential workers“)
But I still wouldn't say that group is the one that cares about crossing between transit areas.
