I believe the 2002 Japanese Grand Prix had zero (nope, that’s no error) overtakes throughout the whole race. I remember watching this race Sunday morning, when I was a kid. I was a Ferrari fan, but even for me that was a horror show.
Although in my opinion, what really makes F1 exciting is a competitive field where many cars can win. In 2002, every race was the same crap. Schumacher leads Barrichello, the Williams’ of Montoya and Ralf behind, then the Mclaren’s of Raikkonen and Coulthard, then a very noncompetitive and spread out midfield, then Minardi. The whole season in general was a dreadful disaster, all the more ironic given that the season following it (2003) is still, to this day, the best F1 season I’ve ever seen.
If I could chose between having overtaking, versus having a competitive field. For me, the decision would simply be too difficult.
