I don't see how these services can compare with a private car without totally saturating the neighborhood with lots of idle vehicles sitting around

Are there not giant parking lots and over-capacity street parking in your city? I live in the US suburbs, own a car, and it sits idle the vast majority of the time. Individual car ownership literally leads to the problem you claim MaaS creates.

Absolute opposite - minimal parking lots and severe under-capacity for street parking. Off-street parking for 1 maybe 2 cars can reach prices of over £600,000 (approx $1 million) [1] in central areas.
