I'm surprised that there aren't straight disqualifications for more than some number of grid places in terms fo penalties. Why not just straight up do a race ban?
That's needlessly harsh for teams that have an unreliable PU. That's why the penalty actually goes down for the second component over budget (5 spots for the ICE instead of 10).
Why? What’s the incentive to do that? That’s how you get a sport where the teams besides managing their tires will baby their engines even more. It will just increase the gap between the top teams and bottom teams. It would make the sport boring to watch, and halfway the season multiple cars will be missing from the grid.
