I was waiting for a last few races last year for this to happen so I could write about it, and then when it happened I forgot...
Norris' win in Australia in the first race of this season ended the streak of 15 races without the same winner in consecutive races (no driver won two races in a row).
I thought it might be a record, but it's not even close
Length of streak / seasons when it happened:
28 during 1982-83
23 during 1973-75
19 during 1977-78
18 during 1958-59 (minus 2 if you don't count Indy 500, but the streak would still stand at 16)
17 during 2011-12
16 during 2009-10
15 during 2012-13 and 2024
What's funny is that the previous 15 race streak in 2012-13 was followed by a 9 race Vettel win streak
