Usually I open carry a Grand Chetokee but i was thinking about getting a Smart, more conceivable. When I travel by air I may rent a vehicle after I land , no fingerprints needed, just a current DL. Hard to take it to the hotel room though. For travel overseas I may decide to get an international DL even if it may become difficult to rent a car, in some countries (http://www.breitbart.com/london/2017/04/11/ban-cars-newspaper-stockholm-attack/). What do you carry and why?
