Might that be partly because they are a fledgling technology and people aren't as used to them as they are with bikes?
Well, that's why I'm allowing for what I call 'early adoption pains'.
It doesn't necessarily mean that they are inherently dangerous or considerably more dangerous than bikes
I certainly wouldn't say 'necessarily'. This is the real world, so claiming modal necessity for any empirical assertion about it is probably not going to work. :)
As I said, it's simply based on experience (now running nearly into its third decade) with mass electric bike use in European cities. While I don't believe (yet) that scooters will gain the same kind of traction, I think the two phenomena are roughly comparable. Early indications certainly suggests that it's a good comparison.

That could mean a number of things:
It doesn't necessarily mean that they are inherently dangerous or considerably more dangerous than bikes, just that they might need more time to develop as a useful alternative urban mode of transport
