The issue seems to be the webp format. I was also not seeing images on an old firefox version. You should use a picture element, so that you can provide working fallbacks.
There is a difference though, centuries before cars they didn't have trains/metros/drones/airplanes so the streets were the ONLY venue for transportation/logistics, thus necessary.
That said I don't believe a city without cars will work unless it's planned for that before building. Basically all everyday logistics would have to be underground. Obviously it would only work for very densely populated areas.
I'd like to see something like that though. Small densely populated areas connected by trains/metros and surrounded by forests.
Describes perfectly some problems I've had when sleeping. They are not really any problems I think before sleeping and even in my sleep I'm not sure what the problem is but oh boy is my brain thinking hard about it. Usually I need to reset by walking around my apartment for a minute. Thankfully I've had less and less of these nights recently.
Pretty much only for modding software/games that provide a lua API. If I were to create a software like that I would definitely consider implementing a scripting interface with LUA.
When I was on exchange in Japan my underage friends from joined me multiple times for bars and not a single time was their ID's checked. I've only had my ID checked during some special event like Halloween in very central areas in Tokyo.
In stores they will not even check ID's or ask your age verbally but you just tap a button that says you are old enough to buy alchohol.
I would be very careful about adding a copy to clipboard feature in a website like this. At the very least i hope you will strip newlines in case you implement this. Would be quite awful to copy something without noticing and running it if you mistakenly paste it in a console.
