I think it's particularly a distinctively American concept that resonates with American culture through biker culture. A motorcycle is an independent thing. You're like 'I don't want to ride in a car with this person. I want to be independent and ride by myself. But let's ride in a group. Let's be independent together.'
I don't really make movies because I want to see my face on a billboard or because I want to get good reviews or have a big box office. That doesn't really matter to me at all.
