That chart is disinformation, although driving patterns might produce such a skewed result.
Old Consumer Reports included mileage charts for each vehicle tested: in five MPH increments. Fuel economy always went down as speed increased - even from 25-30 MPH.
The mechanical (friction) load increases in a linear manner, which is not too bad - but the wind resistance increases with the square of velocity, eventually becoming the overriding factor.
Non-programmer-types often think that software design can just be dreamed up from airy nothing, but it is as much a discipline as coding. Find experts familiar with designing and developing software - there are many steps in as many methodologies - and hand over the ball and let someone else run with it. Acquire the business expertise to complement the technical experts or decide you can keep up with the technical wizards.
