Maybe that is the beauty of the carts - peer privileges that are only obtained if you become a pioneer. More pioneers - sell more carts - more inflated hours - WT gets to broadcast more hours spent in ministry - regular JW's believe all of it because there are more pioneers.
Pioneers that were ready to give up - now can go to a park and relax - more bragging rights because they undoubtedly count time from the moment they drag the cart out/arrive at a park. Even if there are several others and they have to wait their turn - it's all good.
My sister and her husband go to San Fran - they get to see the tourists. Maybe they even go around the sights - tho I wouldn't know because they don't talk with me.
