I know what you mean Intricks. I like ideas like this, where you have a kind of more random ride each time as it swings. I don't know how well it would work for a wooden coaster though, as more of the feeling and movement from that comes from the airtime and juddering. Though there are twister coasters that use swooping turns, they're very controlled and few and far between.
There's an X-Car model with "drifting" cars that swing at a pivot point at the front. I don't know how many they've sold, but I think it's in single figures... Like one. It's a similar idea, but the problem is similar in that you're adding such a (relatively) small additional degree of movement that it wouldn't add a massive amount to the actual ride, not as much as a decent bit of track work anyway.
