One of the earliest of these shows was 1968's Wacky Races. This slapstick comedy was able to give the illusion of pulse pounding action and fast paced adventure without actually delivering either. (The children's advocate groups were still not appeased though. Apparently this new generation of tamer show still had too much entertainment value. The networks hadn't sucked out all of the fun, and that wouldn't do.)
For a late 60's cartoon, Wacky Racers is pretty good, though not nearly up to the quality of shows that were on even a few years earlier. The cartoon is an 'eternal race' show, where every week the same racers would compete on a new course. The Wacky Racers are strange characters in even odder looking vehicles. There is the inventor Proffesor Pat Pending in his Ring-a-Ding Convert-a-Car, the Ant Hill Mob, a bunch of midget gangsters in a 1920's sedan, the Bullet-Proof Bomb, the Arkansas Chug-a-Bug held the hillbillies Luke and Blubber Bear, and Cavemen Rocky and Gravel Slag were a throwback to the Flinstones riding in their foot powered Bouldermobile. There were a few more entrants, including Penelope Pitstop in her Compact Pussycat who would later go on to her own show, but the most visible member of the team was the only one who cheated: Dick Dastardly and his dog Muttley in their Mean Machine.
Each story lasts about 11 minutes, and the plots were all the same. The narrator would do some color commentary on the beginning of the race, giving the racers time to show their car's talents. Then Dastardly and Muttley would hatch a scheme to ensure that they won the race: blocking a pass, putting up a fake road sign, or something along those lines. This would invariably back fire, leaving Dastardly at the back of the pack. The narrator would then announce the end of the race.
