We’ve seen our fair share of advanced luggage but nothing quite like the Self Propelled Suitcase.  Built-in to this travel accessory is a tiny electric motor that propels it up to 3 mph.  The motor only engages when the weak and undoubtedly rich – it costs $1,300 – are struggling to pull their precious goods along, when its sensors detect a incline of 15° and 35°  (I guess 36° would be too much of a strain on its servos) and contains more than 15-lbs of stuff.  Additionally, the large and buxom handle is designed to transfer 85% of the load to the wheels.   The rechargeable battery takes 5 hours to charge and produces about 2.25 hours (1 3/4 miles) of juice.
