Right U Right on Mapcat Bowtie

Hi guys, I believe this problem is due to traffic data making Waze think a right, and U and a right is quicker than going straight through the intersection. But since I've been seeing a LOT of these lately, I thought I'd post one up to make sure I'm not overlooking something.

- Just tried to reproduce in live map, failed.
- Checked for soft turn restrictions, none.
- This isn't one of those cheap Chinese Mapcat knockoffs, but a 100% Authentic Mapcat Bowtie hand crafted by the man himself back in May

I don't see anything amiss. I have been seeing many of these as well. I'm very interested to see you are getting them at bowties as that kills my theory that this might be caused by waze not distinguishing between left turns and straight through movements.

While you're at it, make sure that no one can turn left from this segment

Probably. I just wanted to see if there was any other explanation of why Waze wasn't routing straight through (but only some of the time), other than traffic data. I've been seeing these a lot lately, guess Waze has changed something on the routing server to make these more frequent.

I'd also make that second left restricted. There's no reason someone should turn left from that connector.

Digressing from the original intent ... suppose I'm coming to the bowtie from the south and I miss my turn? There are definitely reasons why someone might turn left up there.

As to the original post, has this intersection worked correctly before? If so then the problem might not be fixable in the map. Could the routing algorithms have changed?

Catching up on the forums so I'm late to the party, but I'd say that situation (missing a turn) should NOT be directly handled by Waze. If a driver missed a turn, it is up to them to find a place to turn around -- or just follow a new route. What if the road at the bowtie was blocked off for construction or an accident? Sending the driver back to it won't help. Heck, they could be set into an infinite loop passing through that bow tie over and over again as the driver ignores the turn and Waze just tells them to u-turn and try again.
