yeah this is what biking in my city looks like now on many streets. but at least here people are all on normal bikes.
where I live it would be scooters, e bikes, mopeds, and regular bikes. with half the people on motorized ones, and jamming the accelerator off the line then slamming the brakes at the stop light, because it's a 'race'. also you have the one-wheelers and e-skateboards and all sorts of other random electronic transport device things.
and the worst peopel would be the moms/dads on the e-bikefiets things that flip out you are 'endangering my children' if you are within 5 ft of them. who also jam the accelerator/brakes every light, rather than having any skill.
i miss the glory days of 5 years ago when bike lanes were for bikes and everyone was kind of going the same speed. god forbid.
