In the end, it’s all about the operational costs, isn’t it. Let’s talk about some of the ways to defray those costs, why don’t we. First thing that comes to mind is revenue from advertisement. The bus has all those surfaces on the outside with plenty of advertisement space. And you could also set up those electronic screens with running lines, programmed and priced in real time.
Or how about a second bus trailing the head bus, the second bus operating strictly as a profit centre? A double-decker. The ground deck leases out office space and the upper deck is an outdoor market that leases out stands to farmers, shashlyk-cookers, and people selling “I love NY” t-shirts. The merchants would climb a ladder down to the street and move the merchandise up and down using an efficient compact external cargo elevator.
