It's just that unfortunately the financial system is geared toward making this the "best" option. I don't know about Germany specifically but here for instance if you run a company you can't buy a car and expense it(or get a loan and expense payments for the loan), but a lease is technically a rental so you can expense it, which means that "renting" a brand new car for 3 years is actually cheaper for your company than buying it and keeping it for longer. So yes, you have loads of companies essentially paying for that worst depreciation period in a vehicle's lifetime and then immediately these cars hit the market again.
