What does lightness in the steering usually indicate when driving?

Lightness in the steering typically indicates that the vehicle may be experiencing an icy surface. When driving on icy roads, the tires have reduced traction, leading to a sensation of less resistance when steering. This can make the car feel more "floaty" or less connected to the road, resulting in lighter steering. Drivers should be particularly cautious in such conditions, as this trait can lead to oversteering or loss of control if not managed properly.

Normal driving conditions would generally result in a more stable and responsive steering feel, while low tire pressure might actually cause the steering to feel heavier due to increased rolling resistance. High-speed driving, on the other hand, usually enhances steering sensitivity and weight, also contrary to the feeling of lightness.
