The city core is still recognizably European, with strong street walls, but it is dominated by post-war building facades and, most importantly, massive streets.
In most cities, massive streets tend to be generally horrible. In Warsaw, while they still have their drawbacks, extensive sidewalks and proper cycling infrastructure make these streets surprisingly adequate.
With so many massive streets, the car infrastructure is very generous. And this carried into regular streets as well – creating local streets that are dominated by cars.
