Actually - if you've done it - before landing up a hill is pretty easy. In many cases landing on an uphill slope is likely to be the most survivable option.
The 'ground roll' is very short - done well you can literally 'spot' the aircraft.
As for hazarding some poor sap who is minding his own business - no way. Landing in shallow water or close to shore is highly unlikely to do anything but get you wet.
From personal experience the one thing you cannot count on is people on the ground understanding that moving out of the way is the correct course of action......
