Character mistake: In the scene where the Bandit convinces Snowman to go with him to Texarkana, Texas, to get the beer, he says, "It's only 900 miles there and 900 miles back." In fact, it is only 557 miles between Texarkana and Atlanta, meaning they could cover the 1114-mile round trip in the pre-determined 28 hours in an average speed of 40 mph.
Character mistake: When Carrie says to Bandit "are we doing 110? We're doing 110!" there is a shot of the Trans Am's speedometer. The needle is pointing to 110 on the kilometers per hour dial. On the miles per hour dial, the needle is pointing to a number between 65 and 70.
