Wind tunnel can measure actual forces and yaw on car in gust.

Car stability and handling in wind gusts for yaw angles up to 15 degrees were analysed from University of Michigan wind tunnel tests of a 1/10-scale model car. The model was catapulted through the wind tunnel test section perpendicular to the tunnel airflow to simulate gust conditions. and by varying model and tunnel speeds a wide range relative wind or yaw angles were simulated. A simple interval strain gange balance with conventional recording equipment measured the time history of the aerodynamic side force and yawing moment.
