What they are doing is just the next logical step from personal leases - and it's actually brilliant at that. Instead of say, a lease at $1000/month for a new Porsche, you pay $2000-3000/month for access to almost any model whenever you want it - but I imagine it makes Porsche a lot more money as long as most of the fleet is occupied at any given time.

Exactly. That's the kind of thing (and extensions of) that you could conceivably use a blockchain to support, if you think about decentralizing the fleet.
