From the New Zealand point of view, several things have changed:

- at the dawn of electric fencing, it was common to distribute it via a single high tensile wire quickly added to an existing fence using risers. These could often be quite high so that vehicles could pass under the electric wire at gates, and also so that risers were only needed every 5 or 10 posts. As it was a single wire and the risers perhaps only 2x1s it was not easy to see.

Many was the time, as a lad, that I rode a motorcycle through such a fence by accident.

Hmmm.... reminds me of white water canoeing in the '70's in eastern PA (Neshaminy creek?) one spring. I had the front of the canoe on a fast (spring thaw) but small stream.
Out of nowhere, I saw grass "floating in midair" across the stream. It had caught there when the stream was higher but now the water had receded some and left the grass on the wire.
I barely had time to lay backwards (paddle on top of me, lengthwise) and shout, "Wire!".
It was a barbed wire fence for cattle and it went across the stream.
A wire guide/cutter would have been nice then.

Can't say I ever had an issue with a landing though, but it's sorta like insurance, "You don't like it until you need it".
