As said, very little they publish seems credible to me. I wouldn't be surprised to learn they used Halfords sales figure as a guide to guestimating the quoted 730,000 from other sources, since Halfords have done so well with them while lobbying hard for legalisation.they said in their studies that 94% of the accidents don't involve the hire e-scooters, so they have to make guesses.
Their first guess is 20,000 e-scooters are from the hire companies, 730,000 from other sources.
I don't know how they come up to this estimate.
Only accidents involving hire e-scooters (2.7% of the total of e-scooters in use, from their first guess) are documented.
The rest of their study seems thus result of guesswork.
