Along the same lines, it doesn't seem to account for ferry routes when there is a lot of water in your area. https://oalley.net/map/b4y https://oalley.net/map/b4y Sharing only so the developer has another test case :) The three points on the right are only reachable by ferry, so add approximately 1.5 hrs to the travel time. Plus the one at the bottom right would require the driver to pass through the downtown core of the city of Vancouver; even without the ferry time, it wouldn't be possible to do that in under 1 hour from the origin.

It actually does seem to account for ferry routes. I plugged a location in Seattle in and the surface it draws juts across the water to roughly where the ferries dock. Maybe there just isn't a data source for where you're at yet?

  The more I am seeing examples, and looking at the terrain, it seems like the problem is that it is only acting on the endpoints, and assuming that the map should simply extend from starting point to ending point, regardless of what is between them. But in the truth, it is quite possible to have an endpoint that cannot be accessed in a straight line because you must circle around a mountain, etc. These maps would need to account for those scenarios.

    Yeah, I've seen some strange results as well, such as a large chunk of accessible area jutting through Olympia to Lacey from my starting point in West Seattle where the intervening land is not touched. I don't see how I could get there in 1 hour because the highways all go around the military bases and backwoods there. https://oalley.net/map/b7p https://oalley.net/map/b7p There's a similar blob going from Seattle to Preston, which appears to contain some impossible routes where you would get off I-90 and then circle around via highway. As long as you stay out of the mountains and don't cross any water it seems pretty accurate as a first approximation.

Same, I live on an island it it showed multiple routes crossing the strait where no ferry or bridge exists. Edit: but it did work if I lowered the time. Interesting work though.

Ya I noticed that looking for 1 hour routes from a city next to Vancouver. It got a bunch right but it said I could get out to Powell River in an hour. It's like a 30 minute drive to the ferry, a 45 minute ferry ride an hour drive down the sunshine coast highway then another ferry to Powell river. Everything else around the lower mainland seemed fairly accurate. Though it depends heavily on which direction you're going, at which time of day. Some of those places would take hours to drive to depending on how bad traffic is.
