I don't think this is really to do with tail wheel or tricycle! You could learn in either!
You mention learning to drive a car ? A good example and one close to my heart as in my 20s I was a racing driver in formula ford, formula 3 and clubmans!
Loss of sponsor and a pregnant girlfriend who I married forced me out of racing and I took up flying!
Hence why I argue handling so much in both car driving and flying!
Yes you can teach someone to drive a car but handling a car is a totally different matter!
I would make skid pan training part of learning to drive!
Most drivers with their shiny new licences do not have a clue about handling a car so fingers crossed that they do not get into a situation where the car under steers straight into a brick wall!
With the right teaching and a reasonably competent student they could be taught to fly a tail dragger or a tricycle or for that matter learn on a complex aircraft like a retractable twin ( yes some have done that in the past ) or a Spitfire
It used to be legal to do a PPL on. Twin! Our modern training is a result of our liability mummy state society!
