Question

What do the little metal things on the ground in the pavement do? In F1 pit stops?

Answer 1

its true they are grounding strips to earth the car on refueling so it does not get a static charge and ignight

Answer 2

They ground the car out so it doesn't spark and light up the fuel they are necessary because of the high rate of fuel pumped into the car I believe it's 12 liters/second.

"Cars are fuelled at a rate of more than 12 litres per second"

Answer 3

The first person is right but it isn't 12 litres per second. It's 13. Sorry but i had to correct you.
