I think F1 is at a bit of a crossroads (pun intended). Originally it was used, and justified, as a development environment for road going vehicles. Now that road vehicles have started to go beyond the hybrid technology of F1 it seems no longer relevant, in reality Formula E is probably the real heir. This leaves F1 as a purely entertainment sport, and in my opinion should return to more basic engines with noise, and fumes, and more driver input. Aerodynamics and suspension could still be developed for use elsewhere.
Cheers
