I guess you wouldn't mind losing your warranty on a cat litter machine, but you definitely would suffer losing your warranty on a €20000 car. Although you currently don't have an alternative for that car's DRM, I'm sure someone will come up with something once these get popular enough.

My statements were based on the previous rent-only strategy. Meanwhile, they also introduced the option to actually purchase the battery for ~€4000. As if your handing in your driving data wasn't enough, they can also disallow your charging at any time, and here is an excerpt from their TOS:
18.3 Battery Data
For management, administration, and accounting we will collect information about your use of the Battery and the Electric Vehicle. This
is to allow us to manage battery stocks, maintain hire payments at a competitive level, monitor performance of your Battery and monitor
mileage and fast charge use.
This data will be transmitted to us by the telematic box installed in the Vehicle. If you would like more information about this technical
data, please write to Renault ZE Customer Services, RCI Financial Services, P.O. Box 495, Watford, Hertfordshire, WD17 1GL.
If you have opted to install a Connection Pack we will also receive data about your location. If you do not wish us to receive location
data you may disconnect the telematic box. Instructions for disconnecting the telematic box will be in the Connection Pack.
The cost of leasing the battery for 36 months starts from €79/month (US$104/month) http://en.wikipedia.org/wiki/Renault_Zoe
