I try to not put the cars on a battery tender by using them regularly. But I'd rather be out traveling and not at home.
I like to visit multiple Osterias in one day too. My record in one night was five different restaurants all in the same night. We had a PuristSPro restaurant hopping dinner all over Western Los Angeles and visited four or five Japanese restaurants all in one night. That was a fun night, I still had to drive 400 miles back to San Francisco later that evening. The drive was in a rental car, not a Bentley.
