A lot of cars don't include a spare tire anymore.
Last couple times I looked, it was more expensive to buy the oil and filter than to go to my local mechanic to get an oil change.
I appreciate that it's good to know how to do these things, but it really seems like there's no reason most people need to actually do them with a current model year vehicle.
As someone who lives solidly in corn maze country, this is a well used joke whenever the topic of corn mazes comes up. Which means I hear it about twice a week throughout the fall.
