As a bicyclist I hate them, at least the smaller ones. Because they slow me down, can't take them with 40 to 50 kph, need to slow down to 30. But that was the intent, yes?
However, crossings with traffic lights I can take at any speed I'm able to, when they are green for me, and I don't need to turn. Or if I can oversee them from afar, and they are empty, and I can give a shit about 'lights'.
> any speed I'm able to
Well, provided you can still stop in time should the lights begin to change.
Some roundabouts here have bike pass troughs on the side (obviously only works if there is no turn to that side) for speedy drivers like you.
Other than that it's obviously by design. There is no reason to speed at constant 50kph in a city. Nether for a car, motorbike or e-bike.
The think I don’t like about not being able to “speed” at 50kph(!) through a city is that, at least in Australia with it’s excessive compliment of bureaucratic Karens, is the 30 > 50 > 70 > 60 > 40 > 30 > SCHOOL ZONE > 80 > 40 > 50 > 30 nightmare.
Which does two things, raises state revenue and causes drivers to spend way to much time concentrating on how fast they are going rather than driving to suit the conditions and paying focusing to what’s going on in front of them.
And don’t get me started on the pot holes.
