One idea is the observation that in the USA (at least California), it seems to be common to have compulsory U-turns. On a divided street, the divider would not be interrupted in every crossing, like it usually is in Europe. But in this case, the Hopson Rd/Louis Stephens Road crossing seems to be fully connected both in OSM and in the Bing imagery.
Was your destination to the east? What is the complete calculated route?
The destination was on Louis Stephens Rd south of the intersection. This was the second time I noticed this but I never found an issue in the data itself.
There is a no_u_turn restriction at the south end of the way, added by aighes today. Is this your test if the turn restriction makes any difference? I guess you might want to add no_u_turn restrictions to the crossing as well, because the Bing imagery seems to suggest no_u_turn there. Note that mkgmap currently does not support ways in role=via. Not sure what you meant here. I don't understand why I get this strange behavior just on this way and not on similar ones. I can look up others that are the same where a straight route works fine but I don't recall it right at this moment.
