So when its foggy we go everywhere in reverse?😉
European cars have a back up light and a fog light.

I remember in London during the early to mid fifties I would be on my bike in thick smog and I would have a string of cars following me because I could see further in front of me than the car drivers could. I made sure I did not fall of the bike or I would have been in big trouble. They could just see the the rear light of what was in front of them and having a rough idea where they were they, followed me like the rats in the Pied Piper of Hamelin. I wonder how many people got lost entirely, ending up miles from their intended destination.
Often a passenger would have his head out of his window telling the driver how far he was away from the curb.
The fog was from coal fires, smokeless coal was mandated and the fog went away more or less, you could still smell it though.
You felt completely lost even in an area you knew because landmarks disappeared.
Thousands with breathing problems died in those smogs.
Thousands died in the great smog of 1952 which lasted about four days. People who died just lay there as there was no transport to take them away as London had come to a standstill.
I was reminded of all this when I read ‘Death In The Air’ a book written by Kate Winkler Dawson.
