The poll doesn't address the central issue: What is technology (from a fan's perspective)?
From an audience's perspective, technology has been dead in F1 for a long time. The only "technology" audiences can access is tech that stimulates the senses. We can hear the difference between V6 and V8. Most of us can hear the difference between forced induction and natural aspiration. We can see variance in aerodyanmic designs, and we can see one car pull away from another car during the race. We can see the driver working in the cockpit, and we can get a feel for what kind of driving characteristics the car has based upon how hard the driver works. We can hear how long or short the shift times are and how rapidly the engine gathers speed or decelerates.
For the most part, all of the technology is long gone from the standpoint of the fans. We got nose cone design back, and we boffins can read race mags to gain access to other minor changes, but, for the most part, its just a chorus of identical V6 engine notes emanating from cars that are all very similarly shaped. Only 3 companies supply power-units, the cars are all quite similar to drive (from our perspective). It's like a symphony comprised of 100 cellos. What's the point?
If F1 doesn't bring back variation, it has nothing to offer. Every team has a different budget, different drivers, different engineering philosophies and different goals. They will never be happy doing things one way, and spec components have to be limited as much as possible.
Just set a maximum fuel flow limit and maximum fuel tank size. If the manufacturers want hybrid systems, let them fight amongst themselves as to the common specifications for hybrid systems, and then adjust the fuel flow and tank size to achieve some equivalency. If necessary, establish maximum displacement regulations and maximum v-angle. Not sure about ECU, but it will be less critical if mechanical variation is allowed.
So many teams will want to participate in F1 that they will spill into GP2. GP2 can be liberalized, and replace the defunct F2 championship. The FIA will have a minor league for teams and constructors, as well as drivers. If the GP2/F2 rules are good, too many teams will want to participate in GP2/F2 and national championships will be started.
