I beg to differ, Clearly it is possible, or else Sliverstone and the BRDC would have shown a loss in their year end accounts. This they didn't, they showed a modest profit after operating expenses of £650,000. Not mega bucks agreed, but then not at a loss. Sure further investment into the track and facilities is required, but I have trouble understanding the levels of investment being dictated by Bernie.
Mosley as I understand it, was trying to reduce costs of running a team, not the expense of creating new venues or reducing ticket prices for the spectator. And given that Max was trying to reduce the costs of putting a car on the starting grid, few teams seemed that bothered or in a hurry to sign up to this directive, with perhaps the exception of Williams or Force India. Other teams didn't seem that bothered about the cost or running a team, it cost what it cost, in fact Ferrari objected.
