One on one I generally do get respect. Maybe, like you say, I respect the rules and other riders.
Most people understand an ebike ins't just a bike. We embrace those differences. We ride more often and much farther. The people running the trails know that and they feel they need to take the differences into account. A dedicated mtb rider will ride hundreds of miles a year, a dedicated eMTB rider will ride thousands of miles a year. One us can account for 2 or 3 of unassisted riders, both in numbers on the trails and trail wear.
Most single tracks are built and maintained by volunteers. Even rail trails have volunteer days for maintenance. Having spoken to the managers and volunteers, they understand what the future may be. Instead of a few dozen riders per day riding a few runs each, there could be hundreds of riders riding a dozen runs a day. There's good reason for concern. We can work it out though. More people should mean more volunteers and more donations
