Electric motors are quite reliable and it could possibly descend safely 
if one failed.  It is light enough one could even fit a parachute I suppose.
You're probably right it would be better to land on tarmac or concrete.  
I think vertical takeoff and landing is essential for widespread use and 
then the problem of downwash would be common for any such vehicle.
