maybe its just that I'm in the eastern US, but I've been hiking regularly for years now, albeit not specifically on mountain biking trails, and I've had mountain bikes coming the other direction ONCE and it was someone speeding down a gated (no cars) forest road that was wide enough to get around, though scary cuz they were going fat
the other time a guy was going uphill past us so he wasn't moving fast and it wasn't scary at all
it's hypothetically very scary but I really haven't noticed many people mountain biking out there, I'm probably just doing trails that aren't popular for that though
