No, it was an idiot that injured those unfortunate elderly ladies. The press seems to focus on the method and not the irresponsible person. Substitute ebike with cricket bat, gun, plane, train, or automobile and there is still an idiot involed. A bad day in the press for ebikes so it seems.
Then again we only have this side of the story. Everyday, when l cycle to work, l have to be always vigilant of pedestrians that are oblivious to their surroundings. I know you have seen then too. Too busy texting, talking on their phones, lost in the music blaring on their ipod, those simply not caring to look right or left, and yes the elderly.
The ladies just as well could have stepped in front of him unexpectedly. We will never know. We just know an ebike did it.
