I'll only have one bowl a day usually because I can't smoke and do something at the same time, other than maybe driving (and by doing something, I mean physically moving around or needing to use my hands, not like, watching TV or something). That also includes cigarettes. The only time I almost exclusively smoke a pipe rather than cigarettes, is when I'm on vacation.
It's just too inconvenient to haul pipe shit around all day, so I only do that at home, because for me, it's not satisfying to puff on a pipe for 5-10 minutes and put it down. If just 5-10 min of a pipe could give the same level of satisfaction as a single cigarette, might be more worth it for me. But it takes a good 45 minutes on a pipe to get there, and I can't just take a 45 minute break. I'd also smoke more than one bowl at home if I could stand to smoke inside, or could stand to clench and could stand smoking while doing something else, but I can't.
It might also be different if I lived in a walkable city where the heat index wasn't 100+ °F for half the year and had a good 30 minute walk between places, but I don't and it's a pita to light up for 10 min at a time driving between places when I am out (though 99% of the time, I am on my motorcycle rather than the car).
But, it also begs the question of what is even meant by "traditional pipe smoker", as opposed to "hobbyist" or something.
Either way, I know very few people as it is, and no stranger I ever come across would ever know, they never see it.
