People like owning stuff, and that will always trickle up the ladder depending on your your wealth level and desire.
For majority of people the car ranks right up there with owning a house.
roughly 1/3 of Australians own a house, 1/3 loan leveraged, 1/3 renting. Similarly 1/4 of people with a car have it on finance. A house generally appreciates (over recent history, bubble etc) while a car is almost always a depreciating asset which is where it falls apart on an ownership model.
Its a social pressure to own those things, and people buy in despite the economics saying otherwise. Then convince themselves and others that it was the "right" thing to do with the sorts of misleading arguments flying about in here. Having been in all the different combinations of above (rent/leverage/own house, rent/own/share car) there can be situations where one is more profitable than the other. Trying to make generalizations across "majority" when that is mostly based on feelings/desires rather than financial basics, you can say it all you like. I'll point out how its to (the majorities) financial detriment.
You don't hear horror stories about people paying cash for a car (lemons aside, warranties generally cover that). But there are countless horror stories of people coming-a-gutsa on car loans. They literally make drama stories on the current affairs shows with monotinous regularly.
If you have the available cash, buy the car, it's pretty uch ano-brainer unless you have other cricumstances like you move or change jobs often or don't have the lifestyle etc. Yes it depreciates with time, but it's also a cash insurance buffer that should SHTF, you can sell it and get instant cash. But if SHTF financially and you are locked into a car repayment loan, good luck.
Only with hindsight can you look back and calculate the overall financial analysis. And sometimes, that's not the point.
I would strongly advise people, as first order advice, don't get a car loan. You are way better off buying a junker outright than going into a replayment plan for a new (or heaven forbid, used) car.
Obviously things have changed recently, but for many years, people with "good credit" could get new car loans with interest rates below 1% and sometimes even literally 0%. Now of course the car manufacturers offering these loans did so because they knew it would sell cars, and the low/no interest rate would make the upsell into a higher trim level or into a higher-end model easier. Financially savvy buyers could take advantage of these rates and get the car they needed and preserve cash flow. Let's see, would I rather just hand over $20,000 in one lump sum or pay $417/month for four years? (I assume a decent down payment.)
Also re: new vs used, that 0.99% rate is for new cars bought by people with "excellent" credit. If your situation is such that you will be a used car and the loan rate is 8%, then sure, paying cash, even if the car in question has to be a junker to be affordable, is the better option. Where it gets weird is when the price for used cars coming off lease, so three years old, cost slightly under the cost of new, but because the car is used, loan rates will be higher, so in terms of monthly payments and total cost of the loan, the new car might very well end up being less expensive.
And the argument against the junker is that you're buying someone else's problems. You can budget for a car payment, but can you budget a surprise $2,000 bill (or whatever) for a new transmission? Do you value reliability? Do you have the skills, the tools, the time and the space to do the repairs yourself? Can you be without the car for a day, or for the week it takes for you to repair it?
Everyone has different answers to those questions, because everyone's situation is different.
