Generally, if you're serious about getting people were they need to be quickly, you use light rail technology and principles.

Streetcars, in the sense that they're being implemented in North America are no faster than buses in mixed traffic. What they mostly lend is the idea of permanently high frequency transit, which is a positive sign for developers although not as useful for residents as light rail.

Oh sure. I’m talking about lines built in 1890-1925 to take folks from the center business district to 1-4 family detached housing.

These lines stuck around until the late 1950s, and had dedicated lane ownership. The city I live in is small and was demolished by urban renewal, so as suburbs that were a 15 minute drive away developed, the system declined with the central business district.
