McCarty, 468 U.S. 420, 436, 104 S.Ct. 3138, 3148, 82 L.Ed.2d 317, 332 (1984). To leave the scene of a traffic stop without express permission would risk being pursued and stopped again.

See State v. Hernandez, 954 S.W.2d 639, 644 (Mo.App.1997) (<HOLDING>). As stated by the United States Supreme Court
