Don't believe covid testing is the relevant point. Speedway can not pay without crowds, struggling even with them. An October start would be too late for a meaningful season.
The post you refer to suggests only the top 50 in the world. If there was such a list, how many of them would be riding in GB. Possibly only Doyle Pedersen Lambert?
Utility companies will not be making as much money from businesses though. Sports channels will be saving money. Presume they will not be paying for the rights to show live events, currently, and will not be incurring production costs.
BT and Sky may not be under any legal obligation to cancel subscriptions for anyone under contract. However, they should remember that these contracts do not last forever, and how they treat us now could affect how much business they have in the future.
Just read that Sky may let you suspend your account. Not sure how that would work though, if you wanted sky for the films, but did not want to pay for sports until live transmission can be resumed.
I suspect Sky and BT will try to get out of paying for the sports they are unable to show. They may also save on production costs, camera operators commentators etc.
I remember fans complaining years ago, that they would like fixtures by Xmas so they could book leave to go to away matches.
Pity they can't be done sooner as tracks need all the income they can get. Or maybe does not matter as much because more fans will have reached retirement age.
Only 4 team places available in premier league and 2 in championship.
