  1. Flying cars will become a reality once they have enough safety features to ensure they won't fall on and kill people the moment something breaks, so I'm guessing we'll have working fusion before then. To say something is never going to happen though is short-sighted when you consider the number of things in the world that we take for granted despite them "never going to happen".

  2. Coaxial helicopters lose yaw and are harder to land if they break in the sky. A regular helicopter can be autorotated to the ground using the airflow over the main rotor to keep the tail rotor spinning, having the tail rotor means the helicopter can point in one direction ensuring enough air flows over the rotor to glide to the ground for a bumpy, but safe landing. If a coaxial helicopter loses engine power it tends to yaw to one side or the other and corkscrews to the ground much faster, this is the reason why coaxial helicopters either fly very low or they fit ejector seats that detach the rotors before launching the pilot(s) away from the craft. TLDR; If a Coaxial helicopter breaks your choices are either hitting the ground hard with the helicopter and breaking some bones or hitting the ground slightly less hard in your ejector seat and hopefully not breaking any bones.
