i think that it’s important to reserve enough space to streets. not to build lanes, but to build cafes and seating banks and trees there. it’s a typical problem of cities that they figure out that there’s not enough space to build trees, bike lanes, etc. after the houses are built. better reserve space first.
this isn’t really a showerthought but more of a general opinion, but i’ll post it here anyways because i don’t know where else to post it. (pls tell me if there’s a better community to post it to instead)
In places hostile to cars, it’s perfectly possible for delivery trucks and emergency vehicles to use streets intended for pedestrians. Trucks make deliveries at early hours before there are many people around, and emergency vehicles use sirens and drive at slower speeds. As far as general package delivery, people just use smaller scale methods.
