Much of what I see these days is related to misunderstanding of science and technology.
Years ago, I noted when the automatic transmission was becoming popular, that an increasing number of people were unfamiliar with engine braking – the downshifting of a manual transmission to slow a vehicle. When engine braking, the brake lights don’t come on automatically, just like with an automatic transmission when you let off the gas to slow.
I can’t imagine how many vehicles that engine braked were rear-ended. So I started thinking about why. Why is it that people didn’t understand that other people with manual transmissions engine braked?
Then I helped people with cars, some older than I, and I was shocked to find that many didn’t know the basics of how a car functioned. Before the electronics took over engine control, you just needed to know that an internal combustion engine required spark, air (oxygen) and fuel. If you lacked one of those, the car wouldn’t start – and even today, with all the electronics, that’s true.
I recall as I was getting out of the Navy helping a Navy Chief with an MR2, and I popped the hood (behind the cab) and he started talking about the black round thing. It was the carburetor, where fuel and air mixed, and when I told him that he dismissed it as knowledge he didn’t need despite his car not working. This troubled me. Why would someone dismiss knowledge?
