This may be easier said than done, but converting roads into shared spaces may be an answer to that.

London for example are phasing in stricter low-emission areas, which should technically mean less cars will be passing through. Eventually, they could re-purpose roads so that the primary function of them is for pedestrians, bikes, bike/scooter storage etc rather than 4+ lanes of car traffic.

That is why I believe it is temporary anyway, it seems natural that cities will head this way.
