And, of course, because of the obvious advantages, I also think that the amount of these public-use terminals should be fewer than the amount of regular StreetTerms, and possibly have a fee to use them, which could charge either a person's SIC, or require an up-front cash payment.
Overall, I think it'd be a good way to help newer characters get into that sort of shit, which'll certainly be getting more popular after Grid 3.0 releases.
