When you present it like that its hard to disagree.

MPT...

By "They" I presume you mean the promoters rather than the riders.  If so, in addition to a lack of vision, strategy and ambition there needs to be added, MONEY or more precisely lack of money.  Whilst recognising that apparently some promoters operate at a loss, the amounts involved are actually tiny in comparison to what levels of investment UK speedway really  needs.  Of course there are some individual owners who most probably do have the right levels of money required, but given the position/ability of the majority of their fellow promoters wisely decide to keep their hands in their pockets rather than deal with futile hopes.   

Give Steve Boxhall a go.

I personally don’t blame him.

Not a very ambitious promoter then
