Context for non-Los Angeles residents: the San Gabriel Mountains are those seen looming behind downtown LA in many photos.

Also probably context for many LA people, as most seem to consider those mountains a Hollywood backdrop, not a place you can be in 90 minutes from anywhere in LA (with favorable traffic).
somewhat sad to say that if you follow the map link (https://caltopo.com/m/4N7A) there's in fact a trail right next to the "point of inaccessibility" that includes trails + roads.
The path was added to OSM two years ago, which is after the analysis was done. OSM is a moving target!
I once made a similar map at work, but for the whole USA. You can view it if you use onX Hunt - called the "Roadless" layer under "Roads Trails & Rec."
This reminds me of something I saw on a backpacking blog sometime last year. Project Remote, a family that's finding and hiking to all the "most remote" place in each state of the USA. Here's some of the statistics:

The most surprising one to me is: Least Remote: Kansas (0.8 miles from a road).
As someone who lives in the very densely populated greater Boston area, Kansas doesn't exactly strike me as a prime candidate for not being able to get away from roads.
Their website seems to have been commandeered by some Indonesian online casino scam thing in late 2024 and is now offline. I'm unsure of the ongoing state of the project.
