Need to get on the public transport building first.
> I mean, not everyone has the possibility of walking a couple of streets to buy a cappuccino and then take an elevator to the office. Try having kids in a city today and then let's talk.
I don't get this comment. Is there no cafe near you? Also, you still shouldn't speed in residential or mixed neighbourhoods, regardless of where you live. Even if your office is further away. People live there. A highway and ring road usually takes you reasonable near you office, for most cities in europe and I bet every city in the US.
> Try having kids in a city today
What's the difference to having a kid in a city in the past? Cars certainly grew bigger and that's strictly worse for having a kid in the city.
I get not wanting your kids to grow up in the city, but that's also your own decision. And if you end up with a long commute others shouldn't bear unreasonable consequences. Others might raise their kids in the city and the kid might want to cross the road (assuming it is old enough) without a fear of death from thousands of cars speeding by.
The science as well, the dependency between impact veolocity and severity of injury and risk of survival of pedestrians and cyclists is fairly well studied and known.
the image there sure does not look like a 30km/h street to me
I've been there (or somewhere in Amsterdam where it looks exactly the same) and at peak hour 50km/h passing by a crowded bicycle path while at the same time there's a tram next to you surely does not feel appropriate. But yes, that could be cultural.
