Continuity mistake: The name tag on Podcast's uniform is always hand-written. When he puts on the scarf to start the final battle, it still is hand-written. When he shows up to smash the cables box, it's now a black and red sewn name, just like the rest of the Ghostbusters' uniforms. According to Ghostbusters Fandom there's a deleted scene where Ray gives Podcast an official name patch.

Continuity mistake: When Manhattan starts to freeze, the car speeds through the streets with Callie and Phoebe in the copilot's seat. In the close-ups, one can see that the place is empty. In some shots, there's a shadow of a bulky object, maybe a dummy of some sort or the driver, but it's definitely not the two actors.
Continuity mistake: When the Ghostbusters win the final battle and face the Mayor, Winston's hand is on his shoulder or not, depending on the shot. This swaps back and forth.
Continuity mistake: After the car makes a U-turn, Callie's arm is not resting on the seat. A shot later, it is. (00:05:51)
Continuity mistake: After the car stops near City Hall Park, its position differs completely between the first and second shot, plus dark skid marks suddenly appear, despite the car not moving.
Continuity mistake: While chasing the dragon, the car makes a left turn, and skid marks from previous takes are visible on the road. (00:06:24)
Continuity mistake: When the movie starts, the car is packed with people. When it skids and makes the U-turn, there's just the driver.
Continuity mistake: When the possessor moves the tricycle down the street to the Ghostbusters HQs, the doors get blown off the entrance, and the Ghostbusters log/sign falls to the ground (seemed like a soft landing, in that it didn't seem to shatter... but when the long shot of the ice/frost proceeding to the firehouse (Ghostbusters HQ) is shown, the fallen signage is nowhere to be seen.
