I feel like having them disappear when anything intersects them isn't really any better than rct3. The rollercoaster supports for me have a lot to do with the general 'believability' of the park. It's fun to think that the rides you create could in theory actually work but when you have multiple coasters in the same place the track just floats around. A more intelligent support system that could detect other spaces to fit the supports would be nice. Would be amazing to see multiple rides create a larger support that they all use when in close proximity. I don't know, just feel like the system in place atm isn't very good.
