The ability to remotely lock down the car, though, probably lowers the default rate and eases recovery of the car, so leasing this car should have lower "bad debt" costs than leasing a non-DRM'd car, making the lease comparatively cheaper than other cars.
Reneging on contractual obligations is something you should only ever do if you're not expecting any payments anymore.
(Of course this would be the situation in Northwest Europe, I'm not sure how this works in the US, so YMMV. And of course, you can bet it's unlikely in the extreme a collection agency will see it like this). This does not constitute legal advice, and I am especially not advising anyone to do anything. I am just voicing a concern. Contact a lawyer before you do anything (there is free legal representation for people having trouble with payments to financial institutions in most locations, use it).
