If that ebiker was riding a normal black bicycle, installed a rear hub that is black, hid that rear hub with a dark color like oak brown rear rack pannier bags, placed batteries inside the bags, and painted or bought a black controller installed under the rear rack, and did a lot of fake pedaling and rode at normal bicycle speeds, there is no doubt at all that ebike rider would be just fine. Surly he could have easily installed a mxus 3kw built for some hill climbing and no would have a clue.
