My son grew up in Anchorage & Juneau, all he ever used was public transportation. Now that he is in Boston he loves not having a car. He hops a bus or takes the metro and goes wherever he wants and doesn't have to worry about parking or he just walks. He is in Norfolk in drydock for a couple of months... even if he had a car, it wouldn't be doing him a whole heck of a lot of good if it is sitting on a pier in Boston while he is in Virginia.
Non-rates going to cutters that are going out for longer cruises, I would seriously try to discourage them from taking a vehicle. They are pretty much tethered to the boat anyway.
