They added a slick track where the karts have little traction and you can practise drifting. That's actually a lot of fun, and not something I've done anywhere else.
Their main kart track sadly got toned down a lot, to the point that it was boring and pointless. I was a full gas the entire time, never had to brake.
They added electric karts that were also underpowered and had no lap times.
The dragsters were still there, but sadly I kept coming 2nd to dragster #1 because even though I got off the line at full speed every time, the other one was just faster and would first catch up and then pass me, disappointing.
fastest response time
But oh well, it was still a fun enoug day out :)
