There are many different reasons to increase font size that have nothing to
do with someone's ability to see to drive.
For instance I'm writing this on a Toshiba m205 tablet pc. The screen is
12.1" measured on the diagonal. The resolution is 1400x1050. That means to
one physical inch in size I have 140px. Contrast that to the typical 15"
laptop with 1024x768 for the screen resolution that has approximately 75px
per physical inch and you should be able to tell that text on my screen is
just over half the size of what the typical computer display is. The laptop
I had before the tablet had a 15" with the same resolution, that means 96px
per physical inch.
Also, there is a little vision issue that tends to hit people after the age
for 40. It is called "farsightedness" which means beyond 2-4' the person has
perfect vision but for the typical reading distance the person doesn't text
well at all. Friends of mine call it the short arms syndrome.
FYI, depending on whether your 19" monitor is a CRT or an LCD you have
between 71 & 77px per physical inch. Not that small in the grand scheme of
things, especially not when compared to a high resolution tablet or laptop.
The person who should scare you to be on the road with is my father, his 21"
monitor is set to 800x600 or he can't read it even with reading glasses.
