These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

Special Effect Failure: As seen in the main page picture, The 53 gumball on Herbie's door is absent in the original film's "balancing" scene. It was a conscious choice: the bottom of the door had to be cropped so the car could clear the ground to do the stunt, which including the number would have called attention to. An odd example in that it isn't conspicuous in the film itself (it's excusable for the time period and barely noticeable in the scene itself), but a still from the scene was heavily circulated promotion and merchandising of the film, even continuing to be used when the movie was released on video.
The 1997 film contains quite a bit of Conspicuous CG, mostly involving Horace. It also shows up in some of Herbie's stunts, and the reveal of Simon's factory.
The scene where Herbie traps Carole at the drive in combines this with Harsher in Hindsight. Imagine you're watching this play out in real life. A car pulls up at a restaurant with a man and a woman inside. The woman wants out but can't get the door open. She becomes more and more frantic, begging and pleading the people on the outside to free her, but no one will help. The only other woman around, the waitress, not only won't even take a second to try and open the door, but scolds her for making a scene. Then she suggests to the man a more private spot where the police don't bother people. Would you assume that the cheeky little car is trying to play matchmaker, or would you think that the guy rigged the door and that this woman has every right to be petrified? Considering that infamous murderer Ted Bundy really did own a white VW beetle...Ouch.
