One thing that varies between metro areas and countries is the pecking order of transportation -- who has the automatic right of way, right to indignation, etc. 

In Amsterdam/Netherlands: Cargo bikes, bikes, pedestrians, cars

In Bavaria/Germany: Pedestrians, public transit, bikes, cargo bikes, cars

In Innsbruck/Austria: Public transit, pedestrians with ski gear esp boots, cars, pedestrians, bikes

In Northern Italy: Taxis, pedestrians (esp. with strollers), bikes, cars

In US: Pickup trucks, SUVs, cars, dogs, pedestrians, bikes

Please add to the list!

Where do electric scooters (e.g., push scooter that has been electrified) go? In Bavaria they are everywhere partially because of rental app platform. We haven‘t seen many since then.
