All I know is my use is allowed. The law currently supports e-bikes on the MUPs, and your opinion as to whether they should be allowed is irrelevant to the topic.
One should learn to not be ruled by their prejudices, insecurities, and overactive imaginations.

The only time I've had an issue with another MUT user while riding an e-bike was long before I actually ever rode one. It was a roadie too ignorant to distinguish the difference between a Dutch bike and a e-bike, who was emotionally incapable of dealing with being passed.

We understand you're a uninformed loud-n-proud Luddite afraid of change and diversity, no need to belabor the point.
