This is true, but I think The Smiler showed us another thing - the builders.It also depends on how good the parks are at taking care of their coasters. I imagine certain parks give more of a :emoji_poop: than others.
I remember during the construction, the engineers on site trying to force the track to fit. Now, it could be manufacturing faults, but the tolerances on track fabrication will be tight.
Chances are the foundations for the footers weren't quite right. Out by half a degree at the footer, and the track connections miss.
Though The Smiler was a fluster cluck of epic proportions from the start.
I've been on smooth Intamin coasters though and it's hard to believe they're by the same company who produced something like Rita or Stealth. However, the restraints on those amplify the roughness, compared to the lap bar restraints on Egf or the Superman rides.
Then there's the way the coasters are forced to do things. The rocket coasters have massive acceleration, which amplifies the shakes because of the forces. Rita is such a right layout for the speed and Icon is forced to squeeze into the area it's been designed into.
It could just be that the ride is a little too tight and fast at times that causes a bit of rattle.
Or, more likely, people need to stop being wusses
