Considering Paris is roughly 10 km across North-South, that's about 12 min/km at an average human walking speed.
So, this city is about 2 km across, which is very small, a village, considering smaller cities are more sparsely populated than an European metropolis.
1/25th the size of Paris is not what I would call a "village". Paris is a huge metropolis. It is a small-medium sized city.
Additionally, Paris is not exactly a demonstration of how larger cities need cars considering that about 70% of its inhabitants commute without using a car at all.
For comparison https://en.wikipedia.org/wiki/Legionowo is the most densely populated city in Poland, it has about 50 000 people, and is about 3x5 km of low buildings. And still about 10% of the city is a forest :)
Cars waste so much space that people are used to bloated cities.
