Sam joins Leo from home to talk about the toughest part of the driving test. Leo says that the written test was pretty easy, but when during the driving test, parallel parking was the toughest. Sam agrees because it's tough to learn to maneuver slowly around tight spaces. That's why manufacturers have been working on self-parking sensors on cars so that the car can park itself, even in parallel parking. But the sensors also help drivers by telling you how close you are. Ford was one of the first to launch it in 2009, and since have added automatic perpendicular parking to the function. Everyone knows it as "Smart Park" thanks to the Hyundai Superbowl commercial.
