In my experience (as a decently fit regular rider riding a lightweight city bike in a city with a big cycling culture and lots of e-bikes around) the only time I don’t get toasted by an e-bike is if the rider chooses not to.
Many basic e-bikes have 250w motors; the Vanmoof’s is apparently more powerful. 250w plus a little extra from the rider is a significant amount of power to put out, in riding terms. Putting out ~300w for more than a few seconds is likely beyond the abilities of most commuting riders. More serious regular riders could likely do it for some minutes, but usually wouldn’t want to do so, dressed in office gear, on a commute.
Last data point: my girlfriend has a big heavy e-MTB with a 250w motor. I have to work hard on a high end CF road bike to keep up out of junctions. Off the line, with the immediacy of the motors power, is actually one of the big advantages.
