The Latest Automotive Features

Tom was riding along in Larry’s new car. As Tom admired the new vehicle, he asked Larry about its features.
Larry listed the usual, then added, “It tells me to slow down as I approach the speed limit. It warns me when I have to stop. It also points out solid no-passing lines.”
Tom was impressed by these new features and asked to see them demonstrated.
“I would,” explained Larry, “but these features work only when my wife is in the car.”
