In-transit transfers is a fascinating idea, but there probably more practical solutions to the problem you're trying to solve. More realistic I think is finding the right size for vehicles somewhere in between the size of a car and a bus: A bus gets you somewhere at maximum efficiency while sacrificing accuracy (walking to and from bus stops) while a taxi gets you somewhere at maximum accuracy while sacrificing efficiency (roads full of single-passenger vehicles). Something like 6-10-passenger vans are probably the right middle ground to maximize both efficiency and accuracy.
