When negotiating a turn and the FRONT wheels lose traction, causing the vehicle to push straight ahead instead of turning (understeer / 前轮侧滑/推头), how should the driver respond?

1. Turn the steering wheel even more sharply in the direction of the turn and apply hard throttle
2. Ease off the accelerator smoothly, decrease the steering angle slightly to help front tires regain grip, and gently brake once traction returns
3. Yank the mechanical handbrake to induce a 180-degree slide
4. Turn off the engine ignition
