F1 should remain the pinnacle of motor racing technology but there needs to be room for new ideas.
The balance between power, aero and good old fashion skill is wrong at the moment and IMO the main cause of issue is downforce there is simply too much of it. Wings should go back to single of 2 surfaces, and there should be no additional small wings attached to the body. The body itself can aid downforce as well as duct air to the necessary places including directed over the wings. Most importantly the air coming off the rear wing needs to be smoothed, it has been done in Nascar for years which is why slipstreaming is so effective in passing.
Engines and drivetrains aren't far off, small capacity turbo hybrids is the way forward but these items must only create drive or harvest braking there should be no blown wings or letting the engine rev when its off throttle to generate additional energy or airflow. The method of storing and charging electrical energy should be open as should the engines other than a fixed size, which also should apply to turbos fixed size single units only.
Tyres is the hardest to solve, they are so expensive that manufacturers will only commit if they are single supply this does introduce a level surface but it doe mean teams have little choice in strategy. The idea of making them wear out faster as they did a few years ago is both stupid and dangerous. It would be good if there were more options and the idea of forcing teams to elect what they need in advance of the race is good practise.
Strategy need to be down to the teams, but with the current computer predictions most teams will come up with the same answer to which is the fastest way through the race. And drivers, well sack the lot of whinging over paid idiots - it would be nice but realistically the best will be the best. Cut down on the technology on the steering wheel, ban two way radios, auto clutch, launch controls, traction control and assisted braking - if these guys are the best let them drive the car. The idea of saving harvested energy and reusing when they want is good, it allows drives to plan there overtakes.
Circuits, they have boundaries, white lines, that determine the track limits - 4 wheels outside these lines, regardless of advantage, should be reviewed by stewards. The only reasons stewards should not awarding a penalty is if a driver was taking accident avoidance or if they were pushed out of bounds by another car (in which case the other car should be penalised). Drivers will soon learn to drive within limits after all they do at Monaco with few issues. This will force all drivers to drive the same track not versions they make up themselves.
Other sports put together a set of rules that work, WEC and Le Mans have grasped all this modern technology and have different interpretations of the rules which make for close racing even after 24 hours. NASCAR and other American championships have made overtaking easier and touring cars have shown how close racing can be had within a decent rule set. Getting the teams to agree to this will be difficult and we might lose some on the way but it does need to be back to a race series of more than just 4 cars.
