Getting home after a few jars of ale

Recalling conversations just after the First World War of how to get home after a few jars of ale:-

In 1919 I remember my elders discussing how a farmer got home after market and drinks in the pub, when he was tipsy. The relative merits of the familiar pony and trap or the new-fangled car were aired and I remember it being said that the farmer’s own pony was a good conveyance home for him, for they just clicked the word to the pony, which would then take him several miles safely home – but it was not like this with the car. I also remember being driven in a pony and trap and the only protection from the rain was a big umbrella held over all the occupants of the trap – a pleasant idea on a sunny summer day, but very cold on a cold wet day.
