In Biggers v. Continental Bus System, Inc., 157 Tex. 351, 303 S.W.2d 359, 365 (1957), the Texas Supreme Court reaffirmed its rule that a tortfeasor "should have anticipated the danger to others created by his negligent act, and the rule does not require that he anticipate just how injuries will grow out of that dangerous situation". (Quoting from Sullivan v. Flores, 134 Tex. 55, 132 S.W.2d 110, 111). In Biggers, the tortfeasor was driving a bus at an excessive rate of speed in its own lane of traffic. An automobile proceeding in the opposite direction negligently knocked another automobile into the path of the bus. In the absence of either of the two factors, the accident would not have occurred. But the Texas Supreme Court concluded that "if negligent and excessive speed of the bus proximately contributed to cause the collision it is immaterial to its liability that the negligence of the negligent automobile driver also contributed thereto or that such concurring cause may not have been reasonably foreseeable. It is a sufficient predicate of liability that the excessive speed of the bus was a substantial factor in bringing about the collision". 303 S.W.2d at 367.
