Exactly; you paid to enter the park, not to ride any particular ride or see any attraction or show. Back in the ancient times, when each attraction had an actual cost attached to it, I believe you might have been entitled to ride again without paying, and if the lines were very long (since this was pre-FastPass as well) to either stay on the ride or get let in the back and get to ride ahead of the line.
Some other random points:
1. 10 minutes delay while on a ride is a minor inconvenience at most.
2. Everyone behind you was also delayed the same 10 minutes.
3. If you want a 'complete ride experience' on Test Track, that INCLUDES a delay!

I think, in all the times that I have ridden it, I have made it all the way through without a delay maybe twice. We usually bet on where we will be when the ride stops (closest to the spot wins, loser buys the next treats).
4. The only places I would consider asking for a FastPass for being stuck on Test Track are in the hot/cold/corrosive spray rooms (if they forgot to turn the effects off, as has happened in the past), or on the heavily banked curve in front, where you are all pushed against the left side of the car (or the person unlucky enough to be seated next to you).
5. There is a difference between asking for a FastPass and 'demanding compensation'; a little courtesy on the guests' part can go a long way to getting what you want, even with the occasional grumpy CMs.
6. Disney's theme park admission prices are not that much more than other parks, especially when you factor in the number of attractions.
7. I'm going to be there in 3 days, na-na-na-naa-nah!!!
