Motor Mania

Motor Mania is a cartoon made by the Walt Disney Company in 1950. In this madcap motoring animation, Goofy (during his "Everyman" period) transforms into a Mr. Hyde-type split personality, when he gets behind the wheel and provides the lowdown on how not to drive safely.

Synopsis
The cartoon shows how the character, as the pleasant, friendly, and good-natured "Mr. Walker", undergoes a change in personality to the belligerent "Mr. Wheeler" when he gets behind the wheel of his car. Mr. Wheeler is self-centered, inconsiderate, and borderline violent. Upon reaching his destination in town (we are not shown the character's reason for traveling) and leaving his automobile, he reverts to the mild-mannered Mr. Walker, whereupon he is the victim of other motorists' unsafe (and sometimes even predatory) driving habits. However, once he returns to his car, he becomes Mr. Wheeler again, seeking to impose his own will upon traffic, to the point of blaming the tow truck that hauls him away for his slow pace after an auto accident.

Trivia

 * This is the first Goofy cartoon to have a fully redesigned Goofy, with a lack of both floppy ears and front teeth. According to The Goofy Success Story, the in-universe explanation for the apparent disappearance Goofy's ears is that, for this film, he had his ears tied above his head and hidden under his hat.
 * This cartoon reveals that road rage is not a recent phenomenon, but an issue recurring with each generation of drivers.
 * Due to its subtle topicality, it and two 1965 Goofy cartoons about freeway safety, Freewayphobia #1 and Goofy's Freeway Trouble, have been shown in driving schools across the continent.
 * This short was awarded the Buyer Trophy for the best film on traffic safety.
 * Mr. Walker makes a cameo reading a newspaper in Toontown in Who Framed Roger Rabbit.
 * A few clips from this short were shown in the House of Mouse episode "Max's New Car".
 * This cartoon short is like when Goofy (Mr. Walker) is a nice Dr. Henry Jekyll-type person. But when he's driving a car and gets into a road rage he becomes an angry (Mr. Wheeler) a bad-tempered Mr. Edward Hyde-type person.
