You should be allowed to, but your hobby shouldn't be funded by the government.
They could save a quid or two by removing all the useless adverts on tv, I bet they cost a pretty penny more than a few subsidised track days. Considering third party sponsership, It needn't cost the government much at all, but it does need to be initiated by them.
Its harsh to call these ads on TV useless. They do help prevent accidents.
A subsidized track day is not cheap in any way. Track rental, security to moniter the event, liability insurance, ect would be a massive amount to spend, especially considering these track days only effect a small portion of the population, rather than the entire population liek TV ads do. Also as explained above, these track days wouldn't do s*** to prevent accidents anyway.
But hey, saving a few lives is nothing if it means a few people can hoon around a track once or twice a year for free.
