What about a new slower tyre compound that the leaders have to put on in the race, but only if they are 30< seconds ahead of 3rd place and that time gap is no greater than the points gap between 1st to 5th in the WDC, but only if - when equalised - the tyre change wouldn't produce a lap time slow than 107% of the current average laptime during that race up until the end the of previously completed lap, not including laps with pit stops or incidents.
I just think F1 needs something like that that fans can understand just sitting at home watching casually.
You should write the rules for next year.
