The rumor was that two-way ramps have caused routing issues.
I don't know the history of the rumor and have no good way to disprove or prove it.
A test case is a two-way ramp of considerable length (say, one-half mile) connected to two short one-way ramps connected to the freeway. When the on-ramp is restricted (closed), does Waze route the wrong way for a short distance over the off ramp to reach the highway?
The problem is that if a turn is permitted onto a ramp, the ramp should lead somewhere. When the one of the two short ramps is closed, the two-way portion might have to be made one-way in the direction that is still open to prevent routing problems.
With a one-way ramp, the entire ramp is either open or closed; thus Waze never encounters a dead-end while traversing a ramp.
