I don't care about how fast Formula1 cars are around a circuit. I do, however, care about on track racing. In my opinion they should focus on reducing the effect aero has on performance and reintroduce the importance of mechanical grip. Too much focus is put on aero grip, and when that happens cars in a train struggle to follow each other and stay close.
I love F1, I've watched F1 since 2003 and when they introduced the new engines in 2014 I wasn't bothered at all. I don't watch F1 to see drivers and cars going breakneck speeds around a circuit and I don't watch F1 in order to hear screaming engines powering prototype machines. I watch F1 to see one team and driver beat the other. The way they achieve that is pretty much irrelevant provided they actually achieve it. Don't, however, take that statement as an admission that I feel nothing must be done to the current formula. More must be done to reduce the performance difference between the teams and increase on track overtaking, and I feel that the best way to do that, as I've stated above, is to reduce aero grip and increase mechanical grip.
At the end of the day which do you want? Close on track racing with excitement and plenty of overtaking? Or an increadible display, or for a better term, feat of engineering excellence? You can only have one, and choosing one or the other will either increase or decrease unnassisted ontrack overtaking.
P.S. the author of the video failed to include the possibility of 18 inch wheels being introduced alongside Michelin.
