As I grew up in a fairly rural area, I canât say how things were in cities. But in the country, folk would tend to drive, have a few drinks and go home. It was not like everyone was shit faced and falling over. There was not much traffic about, if anything people would tend to go to slow and overly careful because they didnât want to get pulled over for speeding.
They werenât safe, certainly by our modern standards, but there was less opportunity for them to smash into each other. They were more inclined to quietly drift off the road into a ditch.
In retrospect, it was utterly stupid, but it was the way things were at the time.
