Let me try to explain why there was no overtaking (although this fits "Is F1 getting boring" topic).
FIA (he) did not lead F1 to this state by accident or due to stupidity, nope, FIA (he) was just piling money and lying to F1 fans. Unfortunately, some teams profited from it, and lack of unity among teams was just what FIA (he) needed.
"Divide et impera"
There is no overtaking precisely because FIA has made cars so similar. The more similar they are, the less overtaking there will be.
To have great racing you need to have different cars, different concepts, but with similar performance.
Similar cars ≠ cars with similar performance.
Similar cars = cars unable to overtake each other.
You need to have cars with similar overall lap time, but not identical performance in all sectors, same top speed, nor same cornering speed.
Not to waste any more words - Dijon 1979. Completely, totally, incomparably different cars:
Renault 1.5l V6 turbo vs. Ferrari with B12 3l normally aspirated. Different aero too, suspension, everything...
