Can we combine both era's? Refueling with better tires from the old days and 1 or 2 drs zones from current era?
Refuelling is rubbish for racing because a light car on old tyres is faster than a heavy car on new tyres. You need high degradation to change that equation, which then makes the tyres fragile so drivers don't want to attack on track.
Refuelling also shifts the dynamic between undercuts being beneficial to overcuts being beneficial. If you undercut an opponent you then have a heavier car losing laptime, you also spend longer in the pits taking on more fuel, and do more damage to the tyres through a heavier car. If you can extend your stint through fuel saving then you get the benefit of more laps at lower fuel levels, less time spent refuelling, a generally lighter car, fresher tyres through most of the race. So everyone pushes towards extreme fuel saving, again the antithesis of good racing.
I think there are some ancillary effects of lighter cars in general such as shorter braking distances, higher corner entry speeds, etc. which will make overtaking slightly harder.
Finally, with refuelling your race strategy is more or less baked in before you start. You can't be as reactive, you can't adapt to what other cars are doing around you. In general you use as little fuel as you can, extend your stint, and hope to get the overcut to make up time and seal your advantage. The refuelling era in the 2000s was generally a dismal era for on track racing. There's the odd bright exception but most races were dull and formulaic, and at the time we were all discussing the end of refuelling rather than praising its existence.
