I personally wouldn't mind if an alliance could safely get across without ramming the opponent at high speed. Also if they could do it without going out of bounds and getting disabled. Nor would I want them to attack us or our alliance partner during this defensive run.
15 seconds is a long time if your autonomous isn't doing or going where you want it to. It can be dangerous if you haven't had the time to try it out. Or if you aren't using sensors to ensure you'll be where you want.
My whole thing this year is penalties. They're huge! if you get 1 - 30pt penalty it's over we lose. So if your allied with us, and you want to take a run across the field. I'm going to ask: Are you going to slow down over there? Are you sure you'll go where you want it to? Will it go out of bounds if it gets hit? Will it attack us? If you weren't sure about these things, I wouldn't want you trying it.

If I'm against a team that draws a penalty on us I'm going into defense mode because they now have to score at least 2 rows to make up for it.

So anyhow I'd suggest if you don't have programmers, or sensors setup to navigate properly. Don't attempt the defensive autonomous. Running wild is just going to get you in trouble. But a little jaunt to the loaders or smacking the hanger off is safe and easy.
