Push to pass? Unfortunately, the FIA aka Fantastically idiotic association is currently planning to use regenerative braking to introduce this push to pass nonsense to F-1.
But in reality, P2P has proven to be counterproductive to good racing. In CART, they've discovered that is it isn't exactly "Push to Pass", more like "Push to Keep Up". End of the day, the slow teams will use up their boost just to avoid looking bad and the top teams would simply use them to keep or increase the gap between them and the slower cars. Besides, it turns racing into a sick arcade joke.
Hate it when some overpriviledged and intellectually under-endowed nincompoops make the supposed pinnacle of motorsport into one sick joke after another.
