Do you expect to land humans on Mars in a whisker less than 2½ years?

I am a huge supporter of SpaceX, but let's consider the challenges. Navigation from Earth to Mars, life support for what, 2 years, landing site on Mars, crew exposure to sudden g-loads after long duration zero-g travel to Mars, space suits on the surface of Mars, propellant manufacturing out of the Martian atmosphere, launching off of Mars, navigation home, hyperbolic entry into earth atmosphere. How about crew entertainment, medical care, communication, mental health.
The list goes on... Solutions to all these issues ought to be demonstrated in flight and in space by SpaceX before they send people to Mars.
