Utter Poo!!!
Speedway needs to be made attractive to EVERYONE.
ABC1s should be attracted, yes - but crucially so should EVERYONE else.
Another thing - where is the money going to come from to 'do up' these Stadia? Speedway is a small Sport with limited income - plus, of course there are Tracks who do not own their own Stadium and have very little influence on infrastructure. They are probably allowed the Track, Pits, a few selling points (food, souvenirs etc.) and that's it.
I don't profess to know the answer - but one thing I do know is that Speedway needs to attract everybody from all socio-economic Groups.
