No doubt about it, How I Learned to Drive is a powder keg of a play. That's because playwright Paula Vogel presents sexual predator Uncle Peck — oh yes, he and his victim are related — with such balance and objectivity. He's a diffident, ultra-cautious fiend. That said, how long can narrator Li'l Bit go on without bluntly rejecting her uncle before we feel — as she will — that she's complicit in her own torment?
