It isn't a matter of choice of how it looks, its how its laid out. Everything in Grid is well a Grid, linear. Im talking mainly about Blackshroud, so I apologize for not being correct with terms. Grid the city is wonderful and nice, but Blackshroud is nasty.
Also I did not say Grid to Uldah took 1 hour, read my comment. I said 30 mins from limsa to Uldah then another 30 making Limsa to Grid an hour.
Also I did this, I even went further:

It is a 30m trip between each "Nation", Grid > Uldah 30m, Uldah > Grid, Grid > Ishgard.
