Why did the cartoon car slam on brakes?

It could be for added effect and drama. The squealing sound makes the scene more exciting and gets the viewers' attention.

It might show a car coming to a sudden stop with smoke coming from the tires and the driver looking shocked.

The cartoons usually show car brakes as big, colorful components with exaggerated details to make them stand out.

Well, in a cartoon, if a car had no brakes, it would probably lead to all sorts of crazy and hilarious situations. Maybe it would keep going and crash into funny places or objects.

It could be that the reporter's questions were too invasive or didn't show proper respect. That might have triggered the slam from Wonder Woman in the cartoon.

The cartoon car might have crashed because of poor road conditions, or a mechanical failure. Sometimes, it could just be an accident caused by unexpected circumstances.

Maybe it ran out of fuel or had a mechanical problem.

Perhaps in the old cartoon, asking not to slam the door was to maintain a peaceful and quiet environment. It could also have been to prevent the door from getting broken or to show good manners.

Well, usually in cartoons, when a car approaches a stop sign, the brakes are shown as being activated suddenly and with exaggerated force. This can lead to the car coming to an abrupt halt, sometimes even causing the characters inside to jolt forward. It's all for the sake of adding humor and drama.

Maybe the character was angry or had some kind of emergency that made them do it.
