Let’s say you lease a car. Six months later, they reflash the software to increase mpg and reduce performance. The mpg didn’t go up much, so they lower the top speed. A month later they decide you don’t need the tachometer or temperature gauges, that they’d rather you had flashier graphics on the dashboard. Then they decide you don’t need so much air conditioning and they cut that back. Then they require higher tire pressure to increase mpg at the expense of ride comfort. Then the adaptive cruise control decides to double the distance between you and the car ahead. They didn’t intend on that, but figured it wouldn’t bother too many people so they’ll let it ride.
Besides, it’s an unbreakable lease. Ain’t nobody goin’ nowhere.
But they’ll lease you next year’s model at higher cost, and by the way, you didn’t really need that spare tire or turbo to actually work, did you?
