"and really don't like public transit."

I don't like bad public transit either.

There could be the option of having personal cabins for yourself.

> Street cars != Intercity Rail

No, but the two feed into each other. Intercity rail loses most of its advantages if you have to hire a car at the destination.

> Also I'd argue street cars are way worse than busses which have route flexibility.

They're better for that very reason. You can move somewhere with a decent commute and know that the streetcar isn't going to disappear at the stroke of a pen.

I know that you were talking about individual commutes here. The city of Oslo, Norway was considering having a shared trunk in one corner, where the metro, the streetcar, and the intercity rail all shared a stretch of track. I believe it was to make efficient use of existing right-of-way. I think that there were problems due to electrification (750 V vs 15 kV) and other political problems.

There is a different section in Oslo where the streetcar and metro share a stretch of track using a clever interlocking.
