>I would feel awkward not offering a ride home from my place or somewhere I’ve driven my car to -even though a run across town to drop someone off could easily turn into an hour round trip for me.

Whaaaat? That is such a bizarre expectation to impose on yourself.

I would never expect to be driven anywhere by anyone. And I'd only ask if I know that they wouldn't need to go out of their way.

But it sounds to me like you just need to stop feeling obligated to offer.
