We tend to gawk at our new technologies in self-admiration, yet it is often obvious that much of what we have created was imagined and executed far earlier with available technologies of the times. And sometimes, the earlier invention is actually even better than the most modern one.
Take parking assist for example. The newest iterations have a computer plus some form of radar guiding the car into a parking space, but still using the conventional method of turn-and-steer. What the new technology does is basically assume that the driver is an incompetent idiot and that the computer can do it better.
But take a look at this 1950’s version of parking assist. I wonder why it was never implemented. Thanks to my MIL for the find.
