I'm not sure yet. The original plan was to create rules straightforward enough to be printable as an a7 booklet at home. The whole thing currently comes in at 8 pages. I'll be adding the printable booklet version soon!
There's plan's to expand the rules with more vehicle examples and some vehicle chase adventures, which would be substantial enough to do a print run, but I don't know when I'll get onto that.
Hopefully that partially helps!
