What is not a recommended practice to avoid highway hypnosis?

One effective strategy to avoid highway hypnosis is to maintain a stimulating environment within the vehicle, which can help keep the driver alert. Cranking up the AC, while it can provide a comfortable atmosphere, does not inherently stimulate the brain or keep the driver engaged in a way that combats highway hypnosis.

In contrast, taking regular breaks allows for physical movement and mental refreshment, which are crucial for maintaining focus during long drives. Caffeinated beverages can provide a temporary boost in alertness, making it easier to stay attentive on the road. Opening windows can introduce fresh air into the vehicle, which might also help the driver feel more awake and alert.

Therefore, cranking up the AC is not considered a recommended practice for preventing highway hypnosis; it primarily affects comfort without actively engaging the driver's awareness.
