They usually zig-zag for 2 reasons: Tire Heating and blocking. The tire heating oonly happens when the safety car is out, and drivers have to reduce their speed and cant pass, so they quickly swerve side to side, which adds extra friction to the tires and heats them up.
Why do F1 cars swerve behind safety car?
During safety cars they sometimes collect debris on the tires, and undulating the tire around is effective at cleaning them. … The drivers swerve back and forth to create additional friction to generate more heat in the tyres to get them closer to optimum usage temperature.
Why do race cars wiggle?
During a race, a lot of debris (such as rubber) gets kicked up to the high side of the track (groove). When a caution is out, the tires are still hot and can collect that debris (nicknamed “marbles”), which can make them very slippery. The wiggling is done to get rid of the marbles.

Why do Nascar drivers push other cars?
The aerodynamics package NASCAR uses at Daytona and Talladega, the two fastest and biggest tracks in the series, creates tight packs of cars running close to 200 mph.
