I don't care if it's throttle, PAS or whatever - as long as it's not going too fast for the conditions. When I feel that nagging "ooh, he's not pedaling" judgment rearing its ugly head, I just tell myself - it's one less car. And that's true - I don't care as long as someone isn't poisoning the air and busting up the roads - as long as they are riding carefully and safely for the conditions and it doesn't have a gas motor, they can ride on MUPS with me or any pathways. You probably never thought about it, but there can be reasons someone isn't pedaling other than just being lazy (which it sounds like you assume). Some people have medical conditions that you may. not know about or understand. For example, I have myasthenia gravis. The more i exercise, the weaker I get. So there are times if I push really hard (meaning I'm not using my motor to get max exercise) I may not have the physical ability to pedal my way home. It's only happened to me once so far, I'm getting better at figuring out my limits, but that throttle got me home on that one day. There are other physical conditions which can limit someone's ability to pedal as well (I could tell you all about them but you probably don't care). My point is just stop being so judgmental about how people ride and instead be glad they are riding instead of driving and that they are still able to enjoy cycling even though their health is a limitation.
