Coincidentally I was watching the BtB tour of BFAL17 (watching, I have it on mute, so I haven’t listened to what they said yet), and at the 1:05 mark they show an amusement park with a rollercoaster.
It’s well done but it also reminds me why I’ve never bothered to attempt a rollercoaster built just from regular Lego parts – it looks impressive and runs fast, but it also looks like a huge effort and expense to build what amounts to a single loop, i.e. not a rollercoaster I would actually wait in line to ride in real life.
