Or maybe this is just their best effort at hitting fleet-average CO2 emissions goals without bolstering EV numbers by giving them away for free. It looks like cheating, but if this gets any kind of traction (and enable more non-poverty-driven carlessness), it will be a much better result for the environment than selling more, but slightly cleaner cars would have been.

Creative bookkeeping by selling to their own rental subsidies is nothing new in the car industry. The BMW carsharing fleets improve on that by not only creating favorable numbers, but also making them take part in a new market that might well be a significant part in future of car usage.
