Factual error: In almost every movie from the introduction of sound on to present day, lightning and thunder happen simultaneously, while in reality there's always a delay between the former and the latter.

Corrected entry: It's very common for shows, games, or movies that take place after the end of the world to still show people using fossil fuels like gasoline and diesel in vehicles. However, with the production of gas having ended, this could not last very long. Even when properly stored, civilian gas supplies would go bad and be unusable after about a year, diesel a little longer but not by much. Private stashes of gas, like in cans, would only last about 5 months. And the military supplies of gas would, at best, last for 5 years.
Correction: Stored gasoline is typically treated with fuel stabilizer (about 2 ounces of stabilizer will treat 5 gallons of gasoline and prolong its shelf-life by years). All of my stored gasoline is treated with stabilizer, and I've used cans that are 5 years old and older. Even untreated gasoline can have a remarkably long shelf-life: Some years ago, I sold an old Volvo that had been sitting in my garage with a dead battery for 11 years; the buyer brought a fresh battery and installed it just to test the starter, to see if the engine was frozen. To everyone's amazement, the old car immediately started, revved and purred like a kitten, burning the gasoline in its tank from over a decade earlier.
Correction: This all highly depends on the quality of the gasoline and the amount of ethanol and its exposure to oxygen. I've heard about jerrycans of gasoline 25 years old still usable. It's also possible to purify the gasoline again so it's usable by filtering it. Don't need a huge refinery for small amounts.

Stupidity: Ground troops armed with semi-auto handguns, automatic rifles and even heavy artillery just keep wasting ammo, barrage-after-barrage, magazine-after-magazine, against giant robots and monsters 100 feet tall, long after it becomes obvious that the weapons have zero effect. This is an ongoing stupidity dating back to some of the earliest giant monster movies, and is still seen in giant monster and superhero films today.

Suggested correction: Surely in the face of a no-win scenario, doing something that may or may not work is better than doing nothing and awaiting your doom. They would be doing everything they could to stop the enemy in the hopes of saving lives. Even if it takes every last round of ammunition, it may eventually be enough to wear down the monster / robot etc.
I hate to disagree. I think one of the best examples is the latest Godzilla movie where they keep firing their hand guns on it knowing it would be better to just get out, there was absolutely no point to do that. Same goes for Man Of Steel.
In everything from old Godzilla movies to modern superhero and kaiju flicks, we see military forces line up and throw every bit of small arms and heavier artillery they have at the giant monsters or giant robots, with zero effect. The military always retreats, regroups, then lines up and wastes all their ammunition again, as if they learned absolutely nothing from the first experience.
In a no-win scenario, you beat a hasty retreat and live to fight another day, hopefully better armed and better prepared next time. You don't hold your ground, futilely trying to bring down a giant monster the size of a Hilton Hotel with small arms fire.
It's strange because I can understand why filmmakers still do this, even though it makes little sense. They are trying to show that the monster, robot, whatever is unstoppable by conventional means and honestly I don't know how you would do that without these kinds of scenes. Even though they are dumb. It's extra dumb to me when you hear the General yell "Stand your ground, men!" or something like that. Or when the cop runs out of bullets and throws his gun.
I've seen too many scenes where they keep shooting, apparently to no avail, BUT there is always the chance that hitting the "monster" in a certain spot could get it to retreat. Instead of just continuing to rapidly fire with the general intent of hitting the monster, it would make much more sense to focus on a possible soft spot, such as an eye. The "just keep firing" mentality does fall under "stupidity." The military should be using a strategy that is rational, and emptying machine guns isn't.

Suggested correction: Hardly always, if the lightning hits right in front of you you hear the thunder immediately. I'd say from about 100 meters you perceive it as instantly, as it's only 0.3 seconds between flash and thunder.

This is a mistake about in almost all movies, not in all thunderstorms. The common mistake in the movies is when lightning isn't hitting 100m away from the character, but the sound is still instantaneous.

I assume it's about thunderstorms in movies. Name an example.

Instant thunder (even at a considerable distance of miles from the lightning or explosion source) is, indeed, a common and probably deliberate error in most films. The reasoning for it is simple: a prolonged and realistic delay between lightning and thunder could change a 1-second shot into a 6-second shot, for example, compromising the director's intended pace and mood for the scene. Steven Spielberg films have utilized both instant and delayed thunder. In "Close Encounters of the Third Kind," for example, when the UFOs zoom out into the distant background (certainly miles away) in a wide landscape shot, they produce a lightning effect in the clouds that is simultaneously heard as thunder. But in "Poltergeist" (a Spielberg film directed by Tobe Hooper), there is a very deliberate scene of characters realistically counting the seconds between distant lightning and resulting thunder. Choosing to obey physics or not is a matter of the director's artistic license.

I posted this while I was watching Death in Paradise, episode 7 of the third season, but really, you have never seen in pretty much any horror or cheap slasher movie whenever there's a storm, the flash of a lightning coming at the *same* time as a thunder jumpscare sound? It's vastly spoofed, even, when some ugly/creepy/terrifying character makes its appearance. One example randomly picked? Dracula by Coppola, in the first 10 minutes, carriage, lightning in the distance, not even a split second after, rumble. In RL it would reach you a couple seconds later. But really, it's such a movie archetype, I am sure you can find it in any Dracula movie.

The Dracula example doesn't really show how far away the lightning is, it could right above them. It's fake as hell, I agree with that, but the fact there is lightning and thunder at the same time without actually seeing the distance is not a mistake to me. It's also highly unnatural lightning as it only happens twice and then nothing, it's not even raining. It's obviously meant to be caused by the evil surrounding the place. The idea is there is constant lightning right on top of them.

There's a scene in Judge Dredd where every few seconds, there is a flash of lightning instantly accompanied by the sound of thunder. It happens frequently in Sleepy Hollow as well.

I know the scenes you are referring to. In both those instances you have no idea about the distance of this lightning. It could be (and probably is) right on top of them. You can hear that from the typical high sharpness of the sound, only heard when the flash is very close. Thunderclouds are never very high in the air so even the rumbling within the cloud itself can be heard, sometimes you don't even see lightning when it rumbles (yet there is). It's a bit far fetched but you could hear a rumbling or the thunder from a previous flash and mistake it for the flash you see at the same time. Can happen when there are continuous flashes.
