Continuity mistake: Carrie is sitting at her laptop eating a blue ice pop. She takes a bite from the top then holds the stick with the rest of the ice pop in between her teeth while she types on the laptop, we see a shot of the screen. When we go back to Carrie she is eating the rest of the ice pop which is impossible because just 2 seconds before it was still attached to the stick. She didn't have time to bite it off the stick because she was using both her hands to type.

There was no time for it to have come from anywhere else, or across from a far lane. The car was not further down the street coming towards her either, as you can see from the long shot. Big's sedan was not present in the street, before it pulled to the curb behind her. (00:14:45)

Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
