I'm not going to input much into this, but it sounds like that's severely optimised play, which is not really the focus of this guide, but rather to give tips to newbies who may be coming in, and they're usually used to Nu-X-COM, or have only played the original.
I have experience with both Nu-X-COM and the older games from when I was a kid, but many don't even have that, and this guide is mostly formed of all the surprising things I've learnt that aren't too obvious. When I recommended XPZ to a couple of people on my discord, they found all these tips tremendously handy, and EVEN THEN they nearly always Game-Over'ed due to negative Infamy, losing their early gals, or Bankruptcy within early months, when playing difficulty 2.
Cali is a great start, and it's A-Tier for that reason, however, Catgirls are very fragile for newbies to operate, and the debt is difficult to handle when they can't make a profit on more debt-free starts.
I will stick to No-Codex being quite a challenge run in a similar fashion. Frankly, I used Big Birds for the first six months for capacity; speed is mostly irrelevant early as a site won't expire as long as it's targeted. Moreover, it works exactly like a classic skyranger, so it's a bit of a comfort pill for newbies. And then you can indeed run cars or Buckaroos.
