It is probably actually the same server (or server farm)...but, different algorithms with different applications of the penalties.

Subtle. Complicated.

real-time server vs normal routing server?

too much repetition. I'll do it, and blame you if anyone complains ;)

Here is a simplified version with repetition for good measure. Any votes AGAINST just shoving this in?
As of November 2014, it is OK but not necessary to allow the U-turn arrow where appropriate, but not necessary. At this time, Waze completely ignores the U-turn arrow in routing. At some time in the future, Waze might become capable of using the U-turn arrow. This advice replaces the advice from June 2014, which was to disable all U-turn arrows. As of November 2014, it is no longer necessary to disable u-turn arrows because Waze ignores them

Perhaps replacing the first paragraph and leaving the second alone:
As of November 2014, it is OK to allow the U-arrow where appropriate. Waze will not route the U-arrow. Therefore, whether u-arrows are enabled or not should make no difference to routing at this time. At some time in the future, when Waze is capable of routing the u-arrow, these will become useful to wazers. This advice replaces the advice from June 2014 -- at that time, waze used the u-arrow in routing, but did not communicate this to the driver.

Fortunately, the lack of u-arrow support can be mitigated with a workaround...


-----------------
Edited 19 Nov 2014 -- use "u-arrow" instead of "u-turn" for clarity; make clear this is a change from the June 2014 policy

that's a pretty clear response. We should definitely update the wiki.

I thought the current "disable all u-turns" policy was in response to this:
DwarfLord wrote:There is the issue discussed in this thread where Waze will provide a route that requires a U-turn but will not give any instructions to do so, which is mind-bogglingly confusing to the driver.


Therefore the decision to disable u-turns everywhere to prevent this happening, and to split roads where U-turns are absolutely necessary -- in effect, the u-turn instructions problem has led to more split roads.

Or the real-time server needs to be updated in line with the normal routing server. Really, that's what should happen.
