have there been more than 7?

Answer 1

if i know there is more than 7,in the 90ties,maybe at the monaco grand prix from 1996,but i'm not sure!!!

Answer 2

Cool question.

Six and seven leaders has happened fairly often.

The 1971 Italian GP had 8 leaders: Regazzoni, Peterson, Stewart, Cevert, Hailwood, Siffert, Amon & Gethin.

Leave this open until Wednesday morning and I'll give you a definitive answer! I'm off to bed now.

EDIT

I think that's it, 1971 Italian GP with 8 leaders. I've found lots of examples of 6 and 7 leaders, but no other 8s. Even the Indy 500s which counted for the F1 championship didn't have more than 6 leaders.
