Sorry I think I shouldn't have deleted this as it may be an on ramp for the other side of the street

I was using Google maps to show the point where the theoretical Gore is and where the junction should be placed. It just so happens that it has the junction closer to where I want it.

This makes it look like the theoretical gore should be where the lane starts to be solid.

And regardless it looks like you should put the junction before the theoretical Gore

Please don't focus on the Tesla, I am trying to make this the standard way of mapping for all cars.

Not sure if you are agreeing here or not.
The physical gore starts where the 22 crosses the 405.
So the junction should be pushed southeast at least to that point.

But the solid white line separating the 2 HOV lanes should extend that junction even further southeast so the theoritical Gore is where I've been trying to put the junction.

At this point.

I put the junction starting where the hov lane has a solid white line here.

If you leave the junction further northwest there is no way to physically or legally get into the lane at that point. You need to enter that lane much earlier as dictated by the line markings.

It looks like the change you made may have broken the Tesla autopilot FSD navigation again at this interchange.
Ive been traveling this road every day for the past 5 years and have been using the carpool lane exclusively with the Tesla for the past 6 months. The 1st couple months my car would always try and get in the wrong far left lane which goes to the 605 instead of staying on the rightmost HOV lane.

After I found out the car uses openstreetmaps for much of the navigation I started making updates and it finally started taking the correct route. Will take another look at it tonight, may try moving that ramp a little more eastbound because that seemed to help.

Ya my Tesla was having trouble with this interchange for a long time always trying to get in the far left HOV lane to the 605 instead of staying on the 405N HOV lane and I believe I finally had it fixed but recently the partial issue showed up when the Tesla was putting its left signal on when it shouldn't have prob due to the lane counts becoming wrong. With my last drive my Tesla did good and dint
Yes the HOV offramp bridge starts a bit further north, I moved it a bit further southeast than needed in an attempt to solidify that lane as a separate entity. Feel free to move it further north again but ideally the cars should pick those HOV lanes quite a ways before they split.

Here is where the ramp really starts raising.
