In Griffin v. State. 614 S.W.2d 155 (Tex. Crim. App. 1981), the defendant took a taxicab at gunpoint and was convicted of aggravated robbery. See id. at 156. On appeal, appellant claimed that the evidence was insufficient to prove the intent to permanently deprive since he only drove the taxicab a few miles away. See id. at 159. The court, however, found the evidence sufficient and sustained appellant's conviction. See id. at 160.
