In 1980, in Sweden, on a foggy night in January, a ship crashed into the supporting arch of the Almö bridge.
A lorry driver on the mainland side of the bridge was creeping along carefully, not driving faster than he would be able to stop within the area he could see ahead of him. That saved his life, and the lives of the drivers behind him, because he was able to stop just a few meters before the missing part of the bridge. He climbed out on trembling knees, and stopped all the traffic behind him that was heading towards the island.
I was living in Sweden then, and I remember the horror of listening to interviews with the people who had been stuck on the mainland side of the bridge, looking out towards the island and watching in horror and dispair for 40 minutes as the headlights from car after car drove out into the fog and plummeted into the icy waters far below.
Ordinary people didn't have mobile phones back then, they had to contact the emergency services, and it took a while before someone from the emergency services manage to contact someone who lived on the island who was able to get to their side of the bridge and block it to prevent more cars driving over the edge.
I learnt to drive in 1981, and whenever tailgaiting drivers tried to force me to drive faster than I felt able to safely stop in the area I could see ahead I took the advice of my Swedish driving instructor and slowed down to a crawl. He said you can't decide the distance between your vehicles, but you can decide the speed. I'd turn off into a layby as soon as possible to let them pass, but I wouldn't allow them to stress me into driving off a broken bridge or slamming into an Elk.
I realised that a lot of people who are driving roads they drive every day, and could "drive in their sleep" don't bother to adjust their speed when driving in fog or torrential rain. Perhaps they have super special eye sight, or radar vision? Or perhaps they are just the kind of people who would drive off the edge of a broken bridge, because they drove over that bridge every day, and they had no reason to suspect it might suddenly disappear. It's why motorway pile ups happen, people don't expect to find a car stopping suddenly, right in front of them.
A friend once told me that she drove over a flooded bridge in central Sweden at 3 in the morning, with her 5 year old daughter asleep in the car, because she was tired and she just wanted to get home, so she gritted her teeth and drove through the dark swirling water, in the middle of the night, in the middle of nowhere. Half way over the bridge she couldn't see any sides of the bridge, just dark, rushing water in front, behind and on both sides, but she was too frightened to stop or turn round so she drove on in as straight a line as she could manage. She had no way of knowing that the bridge didn't curve off to one side, or hadn't been washed away, she didn't even consider it, she just wanted to get home. When I reminded her that a river risen high enough to wash over the top of a bridge will be strong enough to be carrying huge trees and boulders that can destroy the bridge, washing it away, she told me I was being overly dramatic, and nothing had happened so it was all fine.
People prioritise different things. As the driver you are the one who makes the decisions. It's a big responsibility, you have to decide is important to you, and leave the other drivers to make their own decisions.
