Definitely think size of cars should be targeted here. Refuelling can be safe but just because it’s technically possible doesn’t mean it should be done.
I think it would mean less on track overtakes and, whilst F1 is supposed to be endurance to some degree, the length of the races doesn’t mean we need to refuel unlike a more traditional endurance race. Plus you would lose the need for a driver to be able to manage with a fuller fuel load - they could just push for more of the race unless the pushing + lighter car causes more degradation than current “heavier” cars
I don’t quite agree. Fueling would add an additional dimension to pit strategy in combination with tire selection, which would play out on track as greater variation in on-track speed – ie., if you’re on a stint with a harder tire, do you run enough fuel to get to your next tire stop, or go light for extra speed on track and plan for a splash-n-dash mid-stint? The time penalty per kilo of weight in F1 is such that it might be worth the extra time in the pits.
