After watching the video, I was shocked...in a bad way. The beginning of the ride has no test once so every, I'm pretty sure Disney could have come up with something better for that area. After connecting to onstar, the graphics just seem so random. Next, the part where you used to go off the track still remains but makes no sense why (the lack of narration really plays a role in the understanding of the ride). The enviro chambers are really lacking a lot of things...it's so empty. Then, though I will admit that the laser trees are cool, for first time riders, that test will probably make no sense to them because, again, the lack of narration. Finally as many of you have mentioned, the final test brings you from inside a "computer" to the real world...what?!? I understand why the outside was left alone (probably because GM would have to give up alot more cash) but who knows, maybe some day we will see the outside covered.
Overall, I like some elements from the old Test Track then the new one but A+ to Disney for effort and doing a decent job though things could have been better. Also, as someone mentioned before, it will be interesting to see if any of the animations break down and stay that way.
