20Knockout Qualifying Didn’t Work
In 2016, Formula 1 changed the qualifying format quite dramatically. Since 2006, the basic format had been three sessions, Q1 through ‘3, and several cars were eliminated in each session before the top ten shootout in Q3. The knockout format would see effectively a countdown come on screen, and drivers
would have to set a lap time that made them safe before the countdown hit zero. Ultimately, it backfired massively. It lasted for the first two races of 2016, and saw empty tracks whilst the sessions had 5 minutes plus left on the clock. F1 now still runs the 2006 format, which should probably never be tampered with.
