Good vibes,
no most people don't. same as we don't feel the need for twin engines when flying over inhospitable terrain, ie mountains, forest, cities, water etc, pretty much everywhere that helicopters operate!
Not everyone is so concerned that they will be onboard a turbine helicopter when it has its 1 in 100,000 hr engine failure.
considering that 95% or so of accidents are pilots flying a perfectly safe helicopter into the ground/water/wire/structure, wouldn't you be better to suggest that the helicopter has a spare pilot onboard rather than floats?
