I never liked that you could cancel a Barrel roll if it caused you to land on an Asteroid. I mean, just watch where you're flying, if you crash, too bad for you. If you do a turn and slam into a rock, you don't get to switch to a straight to avoid overlapping either.
It prevents scenarios where you would want to overlap things, like ships. For example, if you have a higher PS and make a bad maneuver, you could potentially barrel roll into an enemy ship to prevent it from firing at you. That's clearly not the intent of the action, so while it may not fit thematically, it works mechanically.
I already pasted the barrel roll related paragraph from the FAQ in this thread. How I read it is you may do the template premeasure before committing as stated in the rulebook, then if you decide to follow through an take the BR action you do so in the way described on the competitive play FAQ.
Then you're reading it wrong. The rules don't permit you to "decide to follow through" after you measure. You declare the action, at which point you're committed. Then you measure, and if it's legal you can complete the maneuver. It's very straightforward. At no point in the game are you permitted to use your templates to measure something without having made a declaration first.
