Corrected entry: When Batman is being chased by the police, an announcement is made on the police scanner "Subject moving west on I-17." Odd-numbered interstates run north-south in the US; even-numbered ones run east-west. (01:36:20)

Correction: The numbering system you describe refers to the interstates predominant direction; however, many interstates curve and move different directions for long stretches. For example, I94 is an east-west highway (and is therefore given an even number), but part of it connects Chicago to Milwaukee. This stretch runs due north and south for about 75 miles. Sometimes police will describe the flow of traffic according to their actual direction instead of the name of the highway they're on. (This correction ignores the more obvious explanation: The Odd/Even system is not an absolute. In New Jersey, Route 3 runs east/west, as does southern New York's Rt.287 (which humorously connects directly to New Jersey's Rt.287 north/south- jwrosa).)
