I'm not a fan of Betty Boop, but 'So Does an Automobile' is one of her more enjoyable cartoons. It features Betty in a storyline that doesn't require us to accept her as beautiful or voluptuous. (Honestly: if you saw a real woman who looked and sounded like Betty Boop -- that gigantic head, that tiny mouth, that perpetual whimper -- would you actually be pleased? More likely, you'd scream and run away in disgust.)
In this cartoon, Betty is running a service garage for anthropomorphised cars that look like Benny the Cab from 'Who Framed Roger Rabbit': really more of a car hospital than anything else. As she ministers to the cars, Betty sings a very catchy tune, every verse of which ends with the song's title, and all the verses make comparisons between humans and cars. A person needs some sympathy, and 'so does an automobile'. And so on.
In addition to the very pleasant song -- which keeps Betty from doing her usual breathy whimpering -- there's also an extremely funny payoff gag, which should be easy to figure out if you look at this movie's title while considering the Fleischer studio's penchant for risqué gags. Still, by Fleischer standards that last gag is quite clean. I might even call it "auto" erotic. I'll rate this delightful movie 9 in 10.
