Private cars are banned from the majority of Oxford Street, so actually none of the space is given to cars. All the legal traffic is buses and taxis, which you need if people are to get their shopping home and you have gone and banned cars and made the parking prohibitively expensive.
But today on Oxford street is a bad example to choose. It's atypical. It is also a hellhole. Luckily there are plenty of other places to shop. If it was this bad all the time, then it would be changed. That's something that may happen if they can get rid of the through bus routes down mortimer street or something.
