The trick with the propellers is new and interesting, but I can't help wondering how easy it is to climb in or out.

I'm not looking forward to the crashes that are bound to happen.  What about the people on the ground underneath a crash?

The real trick will be how to not have the idiots in cars on the ground change over to this.
Wait a minute, it is still a plane so everything pertaining to owning, flying, etc should be the same.....so these are just nicer looking Cessnas.
So there really shouldn't be any problems.

Very optimistic.  Having produced a preliminary design for a V/STOL short haul airliner as a final aircraft design class exercise in college, I can tell you I'm not a fan of twin tilt-rotor designs on account of serious stability issues *ahem V-22, ahem*.  In contrast, take a look at all the 4-rotor drones flying out there.

While less efficient, a 4-tilt rotor design is far more stable and safe. It is much simpler mathematically to deal with, mostly due to symmetry, where you can cancel out or ignore certain forces and momenta.

The transition from vertical to horizontal flight is very difficult and when talking mathematically about 3-dimensional dynamics including acceleration (forces), velocity, and displacement of engines, things can get VERY hairy.  Add aero-elasticity to the problem (dynamic interaction and structural coupling between aerodynamic forces and vehicle structural behaviour) and you will have an absolute nightmare of a problem in your hands.

Until soneone door-dings you and the panel won't open to let out the engines.
