You mean the physical quality of the cars and the RCS? They should be getting a look at too.
Let's face it, Test Track as it was was falling apart. It was so stuck in the mid 90s. This overhaul should add more of a timeless aspect to it.
Wait until you see the preshow and line...
Here are my issues with the current ride:
1. Hill climb....too slow, bumps to "boring". As others have said, these two "features" are snoozefests. The hill climb might be more interesting if it were done at a faster rate.
2. Brake tests - Screens often don't work helping explain whats going on, traffic cones sometimes don't work, The track itself gives away what is going to happen. At least this is somewhat "fun" though, except for the crazy hard "off-on" style brake mechanics
3. Hairpin turns - This can be really fun when it works right. However, I have way too many times that we come too close to a car in front of us and we slow to a crawl. This completely loses the fun part of this.
4. Truck "near-miss" - We're on a test track and we almost collide with a truck? Ok, I get it...its supposed to be fun, but as your own video points out, some of the effects don't work here.
5. Barrier test - Shame that the crash test demo in front of you hasn't worked in forever. That's what really made this fun in my opinion.
6. High speed track - Great...when it works. I've crawled around the track out here too. Would be nice if they would punch it up to 70-80MPH to make it as least as fast as most highways are nowadays.
Test Track is a good ride, when it worked correctly. I hope the new ride has much dimmer lighting as one of the worst parts about the current ride is how much it looks like a "warehouse" during the day especially.
