The fog was as thick as pea soup. This was a problem. Gary was driving but couldn't see a thing in front of him. He knew he should stop, but the road was narrow so if he did, it would be right in the center of the road. He was sure that another car would end up rear-ending him, so he continued forward despite the lack of visibility. This was an unwise move.

Driving in thick fog with poor visibility is extremely dangerous and risky. Safety should always come first on the road, even if it means pulling over and waiting for conditions to improve. Taking unnecessary risks can lead to serious consequences.
