Inactive teams still hoarding drivers and staff. Contracts that are unfulfilled ie, no races driven still stay after a year doing nothing. Not realistic. They aren't available for other teams and remain locked out, terrible n00b players that try to sign the best everything with ridiculous unsustainable offers then leave a trail that isn't fixable.
If you miss a race and sponsorship penalties immediately apply, so too should the contract system. Half works, half is broken.
Fastest time sector data on the session page is not up to date, seems random.
