You're driving on a farm road somewhere in the Midwest. Suddenly, you hit a rut and sink six inches into the deep stuff. In a crossover, your chances of driving out of it are fairly slim. In fact, these popular vehicles (essentially, they are a cross between an SUV and a passenger car) have lacked the technical chops to control wheel speed, apply engine torque, and get you moving again. Improved models - the Ford Edge, Lincoln MKX, and Nissan Rogue - use liberal doses of technology to address those challenges.
