I've been watching the earliest seasons--again! But there are still a bunch I have not seen. So this suggestion may have already been taken up.
While there are many teams I have cringed to see, and many I have found delightful to watch, I would really like to see a Race of Favorites: made up of the Racers who have been the kindest, the most courteous, the most likeable. Some might think that without the crazy fireworks of dysfunctional partners, people would not watch. But in this season of social and political chaos, I would so welcome watching people play without
all the drama.
