Streets with parked cars are residential and don’t need better throughput. They need safety rails so little kids can exist without being run over. They need to be exempt from gps routing so people can quietly live their lives.

In some places throughput isn’t needed… safety is.

You could widen sidewalks, place bike lanes, or plant trees in those parking spaces for the equivalent effect. Also the residential dichotomy isn’t true for lots of areas of the city. I live next to an office building, for example.
