That system doesn't seem to take you to every Bucharest address in ten minutes, only popular ones. I picked a few buildings at random in Google Maps and got hour-long L-shaped trips (detours into downtown) that would have been fifteen-minute drives. I don't think any pre-scheduled routes can cover n^2 trips well.

This wasn't my experience when you cross-reference the systems (bus, tram, metro) and consider walking also works.

Yes, if everyone on Earth magically disappeared. If you've never driven in a dense city, it's often faster to just walk alongside the cars than be in the cars.

This is because, again, cars are so unbelievably space inefficient that the space saving of human people versus cars can make up for the multiple order of magnitude difference in speed.
