Too little resistance will make the vehicle hard to control. Good stopping power is also dependent on well-designed shock absorbers.
Poor contact causes ABS to engage prematurely extending braking distances.
Well-designed shocks in good condition are critical to good stopping power. Due to a high center of gravity, SUVs rollover much more easily than cars. The high seating position also reduces the sensation of straight-line speed compared to a car. Studies have shown that 60 MPH in an SUV feels about the same as 40 MPH in a car. Combine these factors with consumer demands for a softer car-like ride in their SUVs, and potential stability and control problems are inevitable.
