Here is the video in question:
https://www.youtube.com/watch?v=t5hj1TPLfvcNotice the lack of spin with the cars versus the animations we previously saw, granted its partially because there is no weight variance to cause the spinning but that is also part of the magnetic braking system that will control it, I do still see quite a few people being apprehensive about this. I believe it was discussed before on here but I think to help with this issue, the park should market and word it more along the lines of pivoting or turning versus using the term spinning. Again these are NOT gonna be your teacup type spinning cars.
And note too that those launches are looking quite a bit more intense than what the animations showed as well.
