A shot from inside a sedan that Annie is driving shows a nameplate logo on the dashboard that says "Kaiser", but the only cars they are seen driving are the stolen Cadillac, a Packard convertible, a Chevy convertible, what appears to be an old Ford or Mercury convertible, a Ford sedan, and a 1930's Plymouth sedan.
Cadillac stolen from Illinois man that was used in bank holdup (featuring the single take) had a silver ashtray at the top backside of the front seat for rear seat passengers to use (and visible when car first seen at hitch-hiker pickup) but in the holdup scene it is gone.
When Bart grabs Annie arm to prevent her from shooting an employee of the bank as the alarm sounds, they run to their getaway car and you can see the camera-man's reflection for a moment as he rides past the window on a dolly.
After Bart and Annie ditch the car in the mountains and are on foot, Annie says she's tired. He tells her it's because of the altitude. At the end they're in a swamp. A swamp in the mountains at high altitude?
[Incorrectly labeled a goof.] Anyone who has done even a little mountain hiking knows that alpine marshes and swamps are quite common, especially in California.. All it takes is a shallow depression that fills seasonally with snow melt. Many (not all) alpine lakes have adjacent marshy areas. There is no suggestion in the film that the "protagonists" are at an altitude sufficient for permanent snow cover. Consequently, movement into a marshy area for the final scene is not a goof in any sense.
