When you hear a story like this about LM, I always think how it would work with the French, after all the largest number of spectators.
They will hate it and vote with their wallets.
We don't buy that much on the circuit, if this came in, even less.
The only way that the ACO could protect the spend of the spectators would be to have draconian rules and searches to stop food and drink being taken through the gates. Which again the French section of the crowd with their picnics and bottles of red, would take a very dim view to.
