F1 cars should require the greatest skill levels to drive quickly. Today, it's just about the opposite.
A lot of things could be done to make F1 more enjoyable to watch. Here's just a few that have been suggested by others.
Limit aero developed downforce. Flat bottoms, no ground effects. Limit total square feet of aero aids (wings, tabs and spoilers).
Get rid of the hybrid nonsense. They have Formula E for those who like racing exotic golf carts.
A simplified engine format, aimed at keeping costs low. No mandatory fuel stops, ditto for tires. No single manufacturer for tires. Allow any and all tire mfgrs.
6 speed manual transmissions, with clutch pedal. Limited electronic engine management. No launch control electronics. Limit telemetry to bare basics.
Pit stops... Only three men over the wall to work on cars. Need more people? Take it to the garage.
Qualifying sessions: Drawn by lot. Best of three laps. No 2nd chance qualification. This way, all factors are random based on the drawing. This would tend to put faster cars further back if conditions were not ideal. No qualifying set-ups, meaning you must race what you qualify. Officials can impound the entire field after qualifying if the teams can't be trusted. Only supervised repairs can be made after qualification. Any unauthorized set-up changes result in starting from pit lane with a 10 second penalty (minimum penalty) up to disqualification (maximum penalty), depending on the extent of the changes.
All engine manufacturers must be willing to supply at least two teams (including their primary team), but no more than three. Engines for the those teams will be selected at random, 1 race prior. This eliminates manufacturers from selling second rate engines to customers. No more than 2 engines per car, per race.
I'd like to see F1 simplified. It would draw more entries and privateers. Racing would be more entertaining, rather than a parade.
