That a good question, I'm not sure that honoring any particular turn restriction results in "significantly" increased route. Basically, if a left turn is restricted, you can typically take the detour of three right turns around the block.
However, the turn restrictions do have a significant impact on the routing. For example, take this route
. The screen shot is here as the best route changes a lot:
You are much more likely to get the southern route down 9th street and across the 11th St or PA Ave brigdes rather than the the northern route out NY Ave if the left turn from K to 7th here
is restricted. Currently, it is not restricted and I'm sometimes routed through that turn onto outbound New York Ave when the turn is illegal. When I ignore the turn, sometimes waze simply has me turn on 6th back to NY Ave, but more frequently, waze will have me go down Mass Ave to the 3rd St tunnel and take one of the southern bridges. So that one turn restriction can (sometimes depending on the traffic) result in vastly different routes.
