Rule number 4 for the mentored hunt already takes care of that in regards to kids anyways (still applies to adults/non mentor hunters). In fact the deer drive scenario was also illegal so if anyone does that it just shows they don't care about the rules and probably broke others in the past. Violators will be violators.
Rules for mentor
.1. Must have any valid, non-expired Wisconsin hunting approval, regardless of the type of game pursued by the mentee.
2. Must remain within arm's reach of mentee.
3. Must ensure compliance with all other hunting laws, including season, bag limit and weapon regulations. If also hunting and/or attempting to harvest game while mentoring, has all required hunting approvals for the applicable season (license, permit, tag, etc.).
4. A mentor may not use any deer harvest authorizations issued to the mentee.
5. Must only serve as a mentor for one mentee at a time.
