Ive certainly not seen any evidence that legal spec ebikes are landing people in hospital at an elevated rated compared to legal ones. Oz's power outputs and specs are comparable to here, so I just don't see it.
However, like over here there may be a bew cult of muppetry with people illegally gooning about on what are electric mopeds or motorbikes, and its conceivable that this sort of usage and behaviour might lead to a lot of ambulance rides.
But as for e scooters...
Any idea why they focus on lightweight mobility so much when drivers are being blamed? Did a cyclist run over the editor's foot?
In the 80's there was this big push by EC regulators to make leg protextors mandatory on motorcycles. Thisnis despite their being much evidence that while the may reduce leg injuries they instead tore riders in half at the waist and killed them.
This dragged on for a while and was looking quite serious, until it emerged that the wife of the senior EC officer trying to push these laws through had been caught in flagrante with a biker...
This was cracking on for 40 years ago and I forget the chumps name, but when it came out it was a source of much hilarity (not to mention concern at the power of unelected EC officers, but thats a discussion for the Phantom Zone). Rather embarrassingly, the MP Peter Bottom had been quite supportive of this rubbish.
Anyhoo, point being there quite often is an agenda driving biased, badly presented or simply vindictive drivel like this.
