I think if somehow we could get back to seeing the driver working in the cockpit, like the non wing cars of the 70's it would bring in more new fans. We all talk about how to do just that all the time and no one has any answers...... Remember watching the drivers hustle???? THAT was one of the main things that hooked me and I would wager others.
How about some clear Plexiglas that would "expose" the drivers body and hands...If one team was to do that I would wager they had better have a bunch of T shirts ready.
