Yeah it's the minority who ruins it for everyone. I disagree that cruises 'almost always ended up with a crash'. I used to go to weekly meet ups and cruises and only ever saw one crash. It wasn't even due to someone being stupid but driving at night and not seeing a branch on the road.
If it got organised people would definitely come. Just need to make sure no commos show up as that's the type of crowd who ruins these things.
On top of that it doesn't cost a lot of money to get a days rego for car shows. A mate does it for All Japan Day with his drift car if he can't trailer it in.
