I was watching Hamilton and as he hits a bump in the road a plume of dust from the plank came up from the back of his car. As Kimi went over the bump it sparked. Now I'm just wondering how Lotus are doing this without any sign of dust. I watched both Lotus cars and they both spark I'm just wondering how they do this with no effect to the plank.

It's almost like the 80's and 90's when the cars used to spark like crazy.
