Tidy up descriptions of Y/V necks
** Rationale: Lock levels are used to protect roads and therefore, the roundabout lock level should be set to the highest lock level of the roads connecting to it. For example, if the roundabout connects a street (lock level 1), primary road (lock level 2) and a minor highway (lock level 3), all segments on the roundabout should be set to lock level 3.
* '''Do not add 'Y' or 'V' necks to roundabouts'''
** Rationale: Adding extra and unnecessary segments to does not meet the [[australia:Main_Page#Waze_Editing_Philosophy|Waze Editing Philosophy]] requirements of "usability and simplicity". Extra small segments might look "pretty" but do not serve the purpose of aiding navigation.
*** Example 'Y' or 'V' necks and instead, how a roundabout should be correctly configured.
