According to WSDOT, there were 2 bicycle-related fatalities in Washington state in all of 2023, vs. 218 automobile-related fatalities. So a 100x difference. The data is there if you care to look for it.
The number of bike trips will not increase by 100x only, certainly by orders of magnitude more than that.
Now multiply the 2 fatalities considering 10,000x or even more bike trips...

I find it very dubious to assume that cars drive the same amount of kilometers as bikes in the Netherlands...
I ride my bike just shy of 40kms per commute, the same amount I would drive.
Compare that painful inconvenience to a car accident and it's just silly to call an e-bike dangerous.
I have been in 4 car accidents, and am lucky to be here. You step out from a totalled car, and see the carnage, distress and mess that everyone is now subject to. Traffic has to be redirected, cops show up to take down details of those still alive, EMTs try to find the ways you've been contorted, firemen have to disable the vehicle and clear any fuel and fire risk, the tow trucks scrape the husks of twisted metal off the street so people can use the road again. It's a whole ordeal, and regularly fatal.
Although there are exceptions, usually bike accidents are only fatal when a car was involved. Cars are not safe and never have been, we just accept the risk for the convenience.
