What do the colors actually mean?

[dreev]

Thanks so much for what is indeed a bug report. The only sane thing is for color to represent actual days of safety buffer (red 0, orange 1, blue 2, green 3+) and we are definitely working towards that. There’s a stupid amount of technical debt to deal with and … wait, deja vu:

How is "days until wrong lane" being calculated?

Yes, but it’s a big, very multi-faceted fix that involves getting rid of the whole concept of lanes of the road and how we’ve treated the centerline as most fundamental. What’s now obvious (and thanks to @insti for making the case for this) is that the only thing that matters is the critical edge of the road and that’s what the road dial should adjust, not the centerline. We’re calling this project “Yellow Brick Halfplane”.
