I think Speedway at the moment is in survival mode, and better to have Speedway than none at all.
Its a vicious circle, riders want more fixtures and more money, so promoters need more fans to come through the gate, to pay riders more money, but the fans are not there anymore. It's too late for an overhaul should have been done years ago. Supporters have moved on, kids spend all their spare time on their phones or Xboxes and such like, even when you do see kids at Speedway invariably most of them are running around playing not watching the Speedway, you do not see kids out on bikes pretending to be Woofy, or Magic anymore, there are so many more things for them and adults to do today, not like it was in Speedways glory years.
Promoters to don't help either by raising the entrance fee, that seem to be their only answer to dwindling crowds, with the latest being the avid fan who is probably now the wrong side of 60, is having to pay the same as adults at some tracks, which will probably make crowds dwindle even more. Time will tell.
