The biggest problem with drs is that it is effectively press a button and get ahead of the driver in front. In spain after most of the drs passes the passing driver could return back to the driving line before the next turn. If drs really needs to stay then at least make it so that it automatically turns off once you are side by side with other driver. So isntead of creating effortless and boring automatic position switching the drs gives the driver behind just enough speed to counter the dirty air effect after the last corner.
As far as tech rules go I think the "bad in everyway" hybrids are the worst thing to happen to f1 and racing in the last 100 years. I don't even know what is it that forces tech teams to use those heavy hybrid systems in the cars (probably rules...)? They don't even give enough power to offset their own weight penalty. They are not even worth their own weight in a racing car.
Not to mention hybrid as technology is more boring than the knitting world finals dubbed in sign language. I've actually started looking forward to fully electric racing cars. No longer is the hybird energy just some button you press after exiting a corner to get more straightline speed. There is no deceiving trickery with the power numbers. What it says on the tin is what you get on the driven wheels. Not some momentary peak power number that the car can only do for some 5 seconds per lap while the rest of the time it has some 600hp and not 750hp. Not to mention the lift and coasting to recharge the boredom filled batteries...
With full electric engines the full power is at least available all the time. Driving out from the corners and getting on full power actually means getting on full power. Not using lawnmowers to drive the car out of corners and then pressing a button to turn on the electric motor on the straightaway.
How too fix f1:
- get rid of hybrids (expensive, boring, bad for racing, too much speed of the car is the hands of the engine makers and not the teams. Rbr is totally useless with the renault while merc teams dominate)
- have engines that make f1 worthwhile power (use biofuels, mcdonalds fats or measure the co2 from the exhausts.
- more downforce from the under side of the car, less from the wings
- something needs to be done to lenghten the braking distances
- make the driver's safety cell standardized. Standard cog, standard inertias, standard size so that driver size becomes totally meaningless. For example driver+cell should weigh 110kg
- before each racing weekend all cars must be shown to the public without any bodywork so the people can see different things of the cars
