The analog clock is easier to read under all conditions, unless you learned to tell time on a microwave. More importantly, is visible at all times, even when the engine of off and you are sitting in the car without the engine running. It seems to be universally regarded as an elegant and helpful upgrade to the analog readout of the generic kind which you can find on, for example, the Chevy Cruze.
Not necessarily. When I'm driving on the freeway, I can't be looking at the analog clock for too long to determine the time. It is much better to have the actual, digital time on the screen, in order for one to easily tell the exact time. Also, if I'm just sitting in my car while the engine is off, I would most likely be on my phone. Therefore, I wouldn't need to look at the analog clock.
