Some threads tend to organically evolve. Re pit stops, they have been, and always will be, a part of the sport's DNA. Manual gearboxes are not the answer. F1 is about showcasing technological advancements. 2022 will be an important step in trying to improve the racing. There needs to be a shift towards an emphasis on mechanical grip rather than aerodynamic grip. The problem is that in their current guise, modern F1 cars produce so much downforce that it is impossible for them to follow in close proximity. Also, track permitting, we need to see tracks re-introduce gravel traps. Currently, when it comes to track limits, the balance between risk versus reward heavily favours reward, whereby the long, tarmaced run-off areas afford drivers the opportunity to explore the track limits knowing that there is little to no chance of them encountering any challenge.
Yes in fact most threads end up talking about something totally different to the original post, thank god for Godwins law

I only used manual gear change as an example and perhaps you're right that it would be a retrograde step given the cutting edge nature of the sport but we want to see closer racing and overtaking etc however achieving that has been talked about for years but never really come about as one team tends to have an edge and therefore be dominant.
Occasionally when there is a major rule change it throws the cat amongst the pigeons but often the team that was on top stays on top as they have the best designer
The cars do have massive downforce however I believe they have taken steps in the past to reduce this with wing sizes etc, not sure if it's still the case but at one time the cars would have driven on the ceiling if they could

Evolution of tech and car improvement has seen innovation feed through to road cars such as disc brakes and reliability but the cars being unreliable used to have you still gripped on the last lap even if someone was 30 seconds ahead as they still may not finish, seem to remember Mansell winning by half a lap and conking out at the last corner
