I want to get two more teams fielded for the zoomwagon, so that overall the amount of hours covered within their driving range is MUCH better, but the teams each get stable, predictable time off (at least one hard day off plus a flexible one), and there's still time to maintain the zoomwagon. With that load, they'll need a dedicated mechanic who can handle the machine without wanting to reverse engineer anything or "fix" it to suit themselves.

Finding two more speedster drivers may be easier than finding the mechanic.
