Dust, probably from outside the track
That was my initial thought, but wouldn't the dust blow off almost instantly when the force of the wind rose above the adhesion level and be more widespread across the floor? Given the lateral motion Hulk's car seems to have, wouldn't we also see small trails from other parts?
I'm wondering if Renault consider the driver zeroing the distance on the start line with a button on the wheel as a "direct, deliberate and primary driver action"8.6.3 Any alteration of the driver’s controls may only be commanded by direct, deliberate and primary driver actions
Brake dust from the front wheels which is transported by the y250-type and other vortices perhaps?Wynters wrote: ↑Sat Oct 12, 2019 3:40 pm
I could very easily be over thinking this. Occam's razor suggests you are totally correct.
