@whitequark @siderea It's even more puzzling because Google Maps is perfectly capable of generating reasonable-ish walking directions for the same start point and destination if you ask for walking directions. I just have no idea what's going on with the dotted line in the transit directions; it's not even just a single "dotted line to your destination", it seems to have a waypoint that explicitly leads you astray.
@whitequark @siderea I'll also note that the first time I tried to take this screenshot, Google Maps caused Firefox to bog down, and then crash.
Now, who knows if that's a Firefox bug, or a graphics driver issue, but it's kind of funny when it happened, and it looks like the new Google Maps rendering may be a lot more demanding.
