Really exciting day of racing
The NASCAR and Indy races were incredible right to the finish and the F1 would've been too if not for the
late red flag and the fact they allowed the teams to work on their cars while parked. That allowed the leader to put on new tires instead of holding off 2nd and 3rd for the last few laps with fresher tires. It also allowed one team to repair their damaged wing. It's a BS rule as it ruined the drama and gave those guys a second chance.
In NASCAR if they stop the race for some reason the teams are not allowed to work on their cars until the race starts again. The rule this way ensures the team has to overcome whatever adversity under normal race conditions.
