My phone has 2GB of RAM. That bus would need 500 such phones in the pockets of passengers to have the around same amount of RAM.

Storage-wise, I have ~140GB total storage. I think that's above average, but that bus would still need around 100 such phones.

I don't know how the buses are in your city. In mine, even when people are packed like sardines, I don't think we get near those numbers.

A ferry, then. The ferry in my city carries 2000 passengers when it's full (and it's always full in the rush hour, with one ferry leaving every 10 minutes). Assuming every passenger has a phone, and each phone has only 2GB of RAM, it's already around the 4TB mark.

Your phone is old and behind the times.

That said your numbers are still roughly correct. I don't think you can reasonably fit 200 people in a city bus, even one of those English double decker busses.

Medium-sized city buses can hold about 40-50 people, double-deckers go just above 100 if i remember correctly, but nowhere near 150.
