Thanks!
At this intersection
https://www.waze.com/editor/?zoom=8&lat ... s=70697762 you cannot just drive across to Oak Ln. The geometry just isn't quite there. You'd either have to drive the wrong way S on Grant before getting into the L turn lane, or go around the median and risk being hit by S-bound traffic on the other side, or drivers turning R out of Oak.
Regarding other segments in this lot ... as I understand the Parking Lot Wiki, it seems like one helpful thing would be to add the lanes that run parallel to ECR in order to "capture" the parking lot traffic so it's not messing with traffic speeds on ECR. It would also be helpful to add the entrance/exit directly onto ECR that's used by both the gas station and the rest of the strip-mall's customers.
One final note: while the gas station is "Coast Gas", in the app it's listed as "Houtan Petroleum". I've never heard of "Houtan" and never found any other (current) source that uses that name. (And my spouse - who's lived in this area for decades - doesn't recall it EVER being called "Houtan".) Now, it's possible that there's a Houtan Petroleum corporation behind Coast Gas. But no Wazer will find a Houtan Petroleum anywhere near that corner.
