Articles and statistics about f1 and sometimes other racing series.
But the safety car means one more thing that can go wrong in a race, as you can see in the video:
The race leader instead of the safety car is the second alternative. That actually happens in the formation lap, where the driver on pole position leads the grid around the circuit to warm their tyres. The driver would simply drive around slowly, other drivers would follow him.
But at both alternatives, and the rules f1 is currently using, all the gaps between the drivers are lowered to around half a second, which can get a bit unfair sometimes. That's where my third idea comes in.
When the safety car period would be announced, the cars would automatically start using a system that would limit their speed. The speed would be lower around the circuit, and very low around the danger zone. In case of caution due to too much rain on the circuit, the speed would lower a lot around the whole circuit. The drivers would still be able to brake, and even accelerate in case when it's neccessery (a driver with much higher speed closing up).
