BMW Is Giving Up on Heated Seat Subscriptions Because People Hated Them

This is a most excellent place for technology news and articles.
It is the point when the subscription is paid for lifetime, but the warranty is not.
A subscription fee might make sense if it came with warranty coverage. If the fee is for using some heating elements you already have, but no promises they will actually keep working, then you are paying for something that doesn't track any associated expense incurred on the supplier.
