I would like to see a citation for that. The Scurius trial[1] that another commenter mentioned found no evidence for increased battery degradation. Of course, it is going to depend on a lot of details on how the battery is managed, both for driving and for V2G. Generally, the worst thing you can do is fully charge the battery and then leave it sitting for long periods of time. V2G generally won't do that, but then neither will smart charging, generally. If you take the mentality of always topping up as soon as you get home, however, you are probably going to wear the battery out considerably faster than you need to.
