I was wondering what would be best for F1 over next few years: stable rules or each year you change the rules so that the team have challenges?
Stable rules will close up the gap between the teams. If current rules work and the aero efficiency drops by 50%, a closely matched grid (equalized engines) will provide more overtaking. I was watching on Internet over the weekend some old races from 80s - 90s, and Jesus, there were a lot of overtaking back then. I guess because the aerodynamics was not that important.
