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?
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.
Best regards,
Marko
