I think times have changed. we are all older and drive more dependable cars/trucks now.
When I was 25 and only $2 in my pocket, I NEEDED: a gallon of water, quart of oil, jumper cables or park on a hill, roll of duct tape set of tools, just to get to work.
Now we change car batteries at 5 years working or not, replace tires long before they are shot, and things that strand you like fuel pumps even though they are a pain in the neck to replace. I'm much less likely to pull off the road and run over something to puncture my tires
