Other mistake: During the bar scene when the T-800 is on the motorcycle and the bar owner comes out and fires the gun, Arnold Schwarzenegger flinches, specifically his eyes close. (00:09:30)
Other mistake: Just after the top of the truck's been sheared off, the T-1000 sticks his head back up and pushes the shattered windscreen out. He then steers quite severely right, then left, but given how narrow the area is he's driving down, that would have slammed him into both walls. (00:35:25)
Other mistake: When the aqueduct chase has finished, and the T-1000 strolls out of the fire, the semi is hardly burning in the background. Considering that the semi has just violently exploded, and the small bridge it just crashed into was nearly flattened, it seems odd that it shouldn't be burning (very tricky to see, best use zoom in). (00:38:40)
Other mistake: As the cop is walking towards the coffee machine, he steps on the T-1000 (disguised as the floor). The cop proceeds to the coffee machine and buys a coffee while the T-1000 turns into the cop. The T-1000 only touches his shoe, so shouldn't be able to copy his appearance. (00:51:00)
Other mistake: When the T-1000 walks through the bars at the mental clinic, he gets his handgun stuck in the bars for a few seconds before removing it. In the close-up shot we can see the gun is stuck. But in the wide shot that precedes it, his gun isn't stuck at all. Actor Robert Patrick (T-1000) unconvincingly has his arm wrapped around the bar to make it look like his gun is stuck. (01:02:00)
Other mistake: When the Terminator blows his way into the lab, Dyson stops Sarah from going on, saying "the fire's set off the halon system," referring to the gas which starves the fire of oxygen. However, the subtitles on the DVD say "the fire's set off the halo system." (01:43:20)
Other mistake: In the scene in which the T-1000 arrives at Dyson's home, he sees the files burning in the trash can. We know this is happening as the others are in the Cyberdyne building as the police radio, just a few moments afterwards, calls all officers to the area. There is unburned paper on top of the pile. Given all of the time that they were in the Cyberdyne building, there should have been a large amount of ash in the trash can. There was no sign of strong wind to have blown the amount that should have been present. There is an incredibly small amount of ash in the can when it is shown, it just isn't possible with the elapsed time. (01:44:00)
Other mistake: At just about the 2 hour point, a helicopter crashes into the back of a blue police van with such force that it crumples back the front half of the helicopter's fuselage like an accordion and causes it to explode in a huge fireball. In the next shot, we see that the back of the van has zero damage (from the helicopter crash, anyway - lots of bullet holes, but nary a dent in the back structure, nor even a scratch or burn mark on the dark blue paint). I guess you would call this an impossibility mistake. (02:00:00)
Other mistake: In the tanker truck/pick-up truck chase, after the tanker rams the pick-up and destroys the wooden shelter in the bed, you can see the Terminator turn the steering wheel right but the truck turns left instead. You have to look very closely to see this.
Other mistake: When Lewis looks at the cup that he got from the coffee machine, the cup has two Jacks and two Aces. When he looks at the bottom of the cup, it has a Queen underneath giving him two pairs, but he tells Gwen the receptionist that he got a full house.
Suggested correction: There are more cards displayed on the right side of the 2 aces, we can't see them. There are probably 2 queens there.
No there aren't. There's only 4 cards on the side of the cup. That's the whole point of Wildcard Poker cups, 4 cards with one on the bottom.
Well actually there are 5 on the side of the cup, but indeed that still wouldn't be enough to get a full house with a queen. But still, he is allowed to be wrong.
There's only 4 cards on the side of the cup and the card at the bottom. Https://www.youtube.com/watch?v=ovq9xOQNamk and go to the 00:36 mark.
It's possibly because multiple takes were made of this scene and different cups were used. This can be evidenced by the cup that falls to the floor being different to the one seen in his hand. Presumably, in one take he did have a full house, but they forgot to use the correct cup in the shot that was used.
Other mistake: Repeated footage of a car crashing is used during the chopper/SWAT van chase. The clip is first seen just before the onset of the shootout between Sarah and the T-1000. The same clip is shown a second time as the two vehicles are about to pass up the nitrogen truck just before the chopper flies over a pedestrian bridge.
Other mistake: When John and Terminator arrive at Pescadero, John's hair is immaculate, perfectly brushed, not realistic for someone who's just arrived on a motorbike.
Other mistake: Near the end, after they enter Cyberdyne, the other guard notices the main guard gone. He goes to the bathroom to find him. "Gibbons, you can't leave the desk like that." The interior door is slightly closing when he opens the main door. How is this possible?
Suggested correction: That's explainable by air pressure from opening the outer door causing the inner door to move. They don't have handles and only have to be pushed open so they can be moved by air pressure.
Other mistake: After the Terminator shoots off the first padlock, you see John driving towards an overpass. However, as the Terminator is shooting at the truck, the overpass is nowhere to be seen. Not until it takes the top off the truck.
Other mistake: In the Director's Cut, there is a scene where they "reset the switch." The Terminator tells Sarah and John to "rotate the locking cylinders counterclockwise." But the power tool is rotating clockwise.
Suggested correction: The impression is given that the cop walking over the T-1000 gives the T-1000 the ability to copy him. But in truth we don't actually see when the T-1000 came with the sample of the cop to be able to copy him, maybe he had already collected his DNA beforehand. Far-fetched example is that humans shed skin and hair all the time, if that falls onto the T-1000 that could be enough.

Sorry but I disagree with this correction. If we are going down this road of "but maybe..." then it opens up a whole can of worms for what is a mistake and what isn't. In an explosion, a vase still on a shelf might have been glued but its unlikely. Where does it end? I think the original entry is for mistake is correct based on A - if the t1000 already had his DNA then why disguise himself as the floor? He'd have just killed him when he first got to the hospital and B - Unless we actually see or hear any evidence that the T-1000 would actually behave in this manner then as far as we the audience can believe, it doesn't happen.

It's about plausibility. It's to see if the writers and director actually made a mistake or gave it to our imagination.

Another possibility: people do occasionally touch the sole of their shoes when taking them on and off (or if they're polishing them, or trying to clean something off them). That would leave at least a few skin cells that the T-1000 could thus use as a sample.
Possible, but then people would leave skin cells everywhere. If this was the case, the T-1000 could scan the keyboard of a computer, or door handles to every door it passes through to receive many skin cells of different people.
