A little while back, a great addition to the game was made with the option to become an engine manufacturer. At the time, a new engine manufacturer had the option to earn up to 5 engine pts each day through watching ads. This, in addition to the single pt earned for every league race, allowed a disciplined manager to earn a full 30pt allocation for all tracks in around 5½ seasons, assuning a 22-race season. Since the loss of ads being available to earn ANYTHING, it would now take the same manager 32 seasons to do this
5½ seasons = 4 months
32 seasons = 2 years
This is longer for shorter seasons, owing to the more frequently occurring gap day, with no race pt being earned.
Whilst the bigger question about why some form of ad-based reward system has not been replaced (there's hardly a shortage of games out there where ads are available to earn useful game commodities), I strongly feel that some form of tweak to the no. of engine pts earned per race to lessen that massive disparity. Sure, those with a healthy token balance (or bank balance) can invest a load of tokens into speeding up the process, it should feel remotely achievable to those who don't have/don't want to.
It seems a shame to have a good addition and feature such as this basically limited to those who got in at the right time.
