I'm not sure they'd of gotten the tube at all, unless perhaps to connect to a mainline station for a trip to the country? I still feel it more likely they'd of been driven, either by horse drawn or maybe even car (at least to the station) even in 1906.

I remember some rather old photos with very well-dressed people waiting for the tube... so probably "it depends". Compared to horse-drawn carriages, the tube was fast and not prone to traffic jams.

Most people of that era were "very well-dressed" relative to their wealth compared to today's "pyjamas and slippers to go to the local shop" level of couture, so I'm not to sure how much you can read into that.

Other way round is my understanding. Road based transport was for the poor, especially trams, and the underground was for the fancy folk looking to shortcut past all of that.
