You don't have to be rich to get the latest and best in advanced in-car gadgetry. A smartphone app gives any old rust bucket two key safety features normally only seen in luxury vehicles: a lane-departure warning and driver-fatigue alerts. In cars like Toyota's high-end Lexus range, lane-departure systems use cameras and radar to warn drivers when they veer out of a traffic lane. Cameras trained on the driver's eyes sense blinking that indicates you are drowsy, telling you to take a break.
