Rather javadoc correction.
[BLEEDING/INCOMPLETE] More strict go on vehicles.

Roughly this line of develpment has to do with:
* Prevent destroying ones own vehicle [INCOMPLETE: conflict with older
MC versions.].
* More careful set-back handling.
* Reset the players position to that of the vehicle if the player moves
too far off (likely does not have effect, needs more testing). In
principle this is intended to trigger a teleport, the normal player is
intended to not notice, but no guarantees yet.

Not configurable yet, might not work 100%, yet.
