The average driver today knows shockingly little about their car. It's an appliance. They put gas in it, take it to the dealer for service when the message comes up saying service is due, and that's about it. Checking tire pressures, tread wear, brake wear, oil and other fluid levels, or opening the hood for any reason is not something they ever think about.
They make their payments and trade when the warranty expires. It's an appliance.
That's amusing to me. My spouse and I fix all our appliances, cars included.
This is exactly it. People don't want to think about that kind of stuff.
I was over giving a neighbour a can of spray foam. The complexity of it was no more than that of spray paint. You point the nozzle into the hole, pull trigger, it fills with foam. Done.
They spent more time asking me how to use it than it would have taken to patch the hole (~10 seconds).
