AUSTIN—After cutting off a red Toyota Prius on I-35 early this morning, Austin mother of three, Lana Castleton, gave the other drivers a brisk wave of her right hand to make up for the resulting six-car pileup. “I feel super bad about what happened,” said Castleton, whose inattention to the road caused partial paralysis in a 32-year-old computer programmer from San Antonio whose Prius was forced into a guard rail. Carlton noted that she would have stopped to provide aid if she had not already been late for her tri-weekly yoga class. She explained that she was still in the clear however because “[The wave] is a universally acknowledged way to say, ‘My bad’.”
