Technology in modern cars has come a long way over the past twenty years, bringing a variety of features to make driving more enjoyable, safer, and less strenuous for the modern motorist. Among these systems that have made their way into more mainstream cars on sale is adaptive cruise control, but some car buyers of today might not be aware if their potential new car purchase comes with this rather useful feature, or what it is in the first place. In fact, with cheap models like the Nissan Versa and Toyota Corolla offering it, many people may not even know their car has access to what was once considered a luxury feature.
