From the linked blog, not the copy on EVWORLD, there are notes about the Leaf warranty. It seems like Nissan has self-discharge (at the vehicle level) much more under control.
If the author really wanted a Model X, why wouldn't he just keep it plugged in? The only threat is to people that don't realize this is a requirement.

PS. This reminds me of Martin's "two really nice refrigerators" blog...... Tesla did improve the self-discharge rate of the early roadsters after that.

Notes
Other All-Electric Vehicles
While discharge issues are inherent to lithium-ion battery technology, it’s beyond the scope of this article to address the ramifications for electric vehicles in general. Regardless, a company’s battery management system and obviously their marketing and handling of the situation can vary.
The Nissan Leaf is currently the only other widely available all-electric vehicle in the US. A Nissan Leaf sales specialist was emphatic that their vehicle did not have the discharge problem. The Leaf warranty [Full PDF: Page 9] does however state that the owner must plug in the vehicle within 14 days of reaching zero charge, which does appear to differ from Tesla’s manual that says the owner must do it immediately.

Personal Note
I’ve paid $5,000 for a Tesla Model X reservation. Either these issues will be resolved by the time it’s ready, Tesla will be gone by then, or I’ll most likely give up my spot and get a refund. No one has paid me to write this article. TheUnderstatement.com has no ads or sponsors.
