with Travis v. City of Mesquite, 830 S.W.2d 94, 103 (Tex.1992) (Cornyn, J., concurring) (arguing that officers’ decision to pursue at high speed was “an exercise of discretion”) and Carpenter v. Barner, 797 S.W.2d 99, 101 (Tex.App.—Waco 1990, writ denied) (noting, without discussion, that county constable was protected by immunity when he stopped a vehicle whose taillights were not operating) and Edgar v. Plummer, 845 S.W.2d 452, 454 (Tex.App.—Texarkana 1993, no writ) (“The enforcement of traffic regulations by peace officers involves the exercise of their discretion.”). In other contexts, our courts have held that police officers are exercising discretion while performing their duties. See, e.g., Dent v. City of Dallas, 729 S.W.2d 114, 117 (Tex.App.—Dallas 1986, writ ref'd n.r.e.) (<HOLDING>), cert. denied, 485 U.S. 977, 108 S.Ct. 1272,
