In July 2017 I was at EPCOT for like the 3rd time that year (This time my grandfather had a convention at the Four Seasons resort) and Test Track went down 7-8 times in the span of a few hours. This is one of the most unreliable/unpredictable attractions in theme park history. Every time I get in line I am always expecting it to go down.Every attraction in Future World is looking a bit dire, and Test Track is no exception. I remember when the new version first premiered I was excited about it and gave it positive reviews, but now I feel that the original version would have felt less dated now with only some minor tweaks. In it's current form, it's a weird, abstract, half-baked concept at best, and weird, clunky, and frustrating at worst. Even with a Fastpass, you wait forever for it because of the dumb design room being a huge bottleneck. The cars you design are cartoony and cheesy. You're supposed to learn about the balance between the four categories, but it is not well conveyed and I don't think most people grasp it. Your designs have no impact to the ride other than how it ranks them by their already-determined stats at four points. The first few scenes look pretty cool but then you get to the rooms that were previously hot, cold, and corrosion, and I think about how much detail used to be in them, replaced with almost nothing at all. The first room's effect never even works and the third one ("hyperspectral imaging") is just a moving light behind a static image. Then the rest of the indoor portion just took what was already there and put UV paint gridlines over it. Then it makes no sense to exit the simulation grid and enter the real world.
