What is your favourite way to travel and how safe do you think it is ? I can't think of a better metric than deaths per enjoyment mile . The lower the D/EM , the better. enjoyment mile is one mile times an enjoyment factor. I like to travel by skis, snowmobile, scooter, inflatable raft ( in river ) , bicycle. Driving is fun in rural areas or city streets, boring and alarming in commuter traffic. I hate commercial flying ( boring ).
