Just as the title, currently the best payout from sponsors (including bonuses) is 4.8 million per race.
This is a problem since high grade drivers and staffs costs at least 1.5 million each per race. For those who play with 2 drivers their total expenses per race with high tier staff and drivers would be somewhere around 7.5 million (if all staffs and drivers costs 1.5 million).
Of course this can be lowered by getting staffs and drivers from headquarters, but then again, to get high level drivers and staff we need high level headquarters which costs a lot of time and money too.
This suggestion is to also attract peopleto play 2 driver leagues rather than 1, no need to increase token sponsors as they are already amazing.
