SV: analog vs. digital display of time

Perhaps there could be a difference between time/speed

When you visualize 14:15 digitally this form of
representation does not give you feedback on that
23:59 is the end of the scale. Logically time could
continue to 99:99. However if we assume that you know
how to read the time I think digital works just about
as fine as analog although digital display is easier
to get the "exact time" with.

With speed few cars (unfortunately) goes up to 999
km/h . With an ordinary analog display the speed meter
shows the end of the scale(although not all cars goes
this high).

With analog speed meters in cars we get two advantages
- we visualise the end of the scale in a clear way. We
get a feedback on the acceleration which is easier to
read than fast flipping digital numbers.

I used to have a microwave with analog display of time
(in terms of maximum 60 min). Now I have one with
digital display. The salesman sold it to me with the
argument - it is more exact (although I bought it due
to it's clean look)! Yet I found the old one easier
to use.
