Quite. Most innovation over the history of F1 has come from the lower-funded teams (Brabham, Lotus, Williams), and is quickly banned if Ferrari or Maclaren can't make it work. Ferrari and the other well-funded teams have the money to eke out ever-diminishing returns; Lotus and Williams have to rely on "making turbos work", "ground effects", or "introducing aero", or "dynamic suspension", not to mention strangled-in-the-crib tech such as CVT or fan-assisted aero.
