If the ball does not leave the field, there is no penalty. If you're near the goal kicking like that, there is a net next to the field to block missed shots into the field, as well as memory foam to dampen the impact.

If you miss once or twice while obviously kicking a goal, and it goes out, you probably won't get any penalty (other than the standard ball-at-midfield return method delaying your next shot). If you do it repeatedly, expect the refs to pay special attention to you (penalty and yellow card for <G19>, and/or a possible <S01> for repeatedly endangering field personnel--<S01> carries a penalty, disablement, and a good chance of a trip back to inspection to correct the unsafe operation).

If you're talking having it bounce out of the corral area, you may want to slow it down anyway--it may or may not fall into the category I outlined above, and you don't want to run the risk of a delay-of-game penalty due to not being able to get to the ball fast enough.

To be on the safe side, have a "low-power" shooting mode for the near zone.
