It makes sense to go door to door when people are at home. However, most JWs don't really want to talk to anyone much either anyway. Years (maybe decades ago) some ruling came out to go door to door prior to the "book study" night meeting (8pm) so to go about 6:30pm.(?) That lasted some weeks, but died out. I went with my dad but didn't like it at all, especially as it darkened in the winter by then.
In 1975, a circuit overseer made a ruling during one week, that everyone should work alone, so as to cover the "territory" better, faster because of end "so soon" then. The sisters mumbled to me how they didn't like it. I just settled them down that after the circuit overseer left that we can just go back to working together again. (I had just left Bethel some months prior and had lost some unquestioning spirit by then and was then in a long, unraveling process of questioning thousands of knots and tangles of JWdom.)
Anyway, most JWs don't like going door-to-door, not really.
