I have had my Clarity for 5 months and still have half of the tank from the dealer. So so every day use it meets my needs entirely. I will be doing the first long trip(Canada to Florida next week and look forward to seeing what the car can do in HV mode for such a long trip(2800kms)I will probably stop a bit more often for fuel as the tank is quite small. I hope to do 450kms in between fuel stops. My previous car(Mercedes cla) would do about 525kms before I would consider refueling. keep you up to date.
