Hello! When navigating to places, Waze will route to whichever road segment passes closest to the stop point of the place. It pulls locations for places from its own map (search results with blue dots) and from external sources like Google (clear dots). I found the hotel that you traveled to in the Waze map editor here. Its stop point is closest to the parking road to the east, so it will route correctly, but the Google location is closer to the M4, so routing to that will stop you on the M4, and that appears to be what happened to you.

This is why we now have place linking in the map editor, so externally sourced places can be linked to Waze places and editors can fix problems like this directly instead of editing Google maps. When a user taps an external result that is linked, they will be routed to wherever the Waze place is. I can't edit in the UK, but to solve this problem, an editor with rank 3+ should link the Google place into the Waze place, and the Waze place's stop point should probably be moved over to the front door for good measure. Otherwise if that parking road gets moved a bit, routing for the hotel would go back to the M4.

I have requested an update in the UK editor request forum, so I'm sure someone will fix this soon.

Thank you for fixing this, Twister-UK.
