The biggest danger here is not terribly clear. Somewhere in the intersection of people cluelessly walking into the bike lane and bicyclists hitting the clueless.
Looks like bicyclists are the clueless...bordering on criminal:
Have you tried biking at 60km/h? Even on a very good bike with a gigantic gear ratio I don't think you'd manage to get close to it on flat ground.
Quick edit: just to give you some figures, if the bike + cyclist weighs in total about 80kg the cyclist needs to sustain an output of about 1000W (on an aggressive position down on the drops) without wind to ride at 60km/h on flat ground. Very few people on Earth can do that...
Most "cyclists" are now actually drivers of light electric motorcycles. A $1500 Chinese ebike will do that easily.
Riding at 60km/h on a bike consumes a lot of power, aerodynamics are a bitch of a force.
I used to cycle and I don't think I could achieve 60 on flat ground like Amsterdam. That's very solid sprinting that even the best cyclists in the world can only achieve for short periods of time. On narrow Amsterdam streets with cobblestone? Impossible...
And you can see here "normal" bikes clocked at 36 Km:

you get hit by one of these silent missiles, with an 80kg passenger on it, you spend weeks in hospital...you are older person, its life threatening...
Amsterdam bikes are terrifying :-))
These bikes are not going at 36 km/h, whatever device she is using to measure it is incorrectly calibrated or simply not made to measure people on bikes.
That's not a bicycle, that's a motorbike.
"Cyclist" and "someone on an illegal e-bike" are not one and the same thing.
> And you can see here "normal" bikes clocked at 36 Km:
No, those people freewheeling on a regular city bike on relatively flat ground are not doing 36 km/h. That's around 20 km/h by my somewhat well tuned eyeballs. Have you never been on a bike and measured your speed?
You're not going to be seeing cyclists going 36 km/h beyond significant downhills or sporty people on drop bar bikes putting in significant effort.
