I'm a long time diehard F1 fan and the last several years have been mighty slack in the on track battles department.
I think it went downhill when they decided to cut costs and make all the cars similar.
Now they are going to get rid of refueling, so I guess you are going to have to find a way to pass somehow with possibly less pit stops to make up time.
Pit stops will be shorter, too. That will also reduce the possibility of making up a spot during one.
And with more cars on the track, I suppose it's bound to get interesting without refueling, one way or another. 😀
