Real world Visibility question

On a nice day with good visibility ,at what altitude do you loose sight of a
2-lane road say a state highway?
Or put a different way if I want to use a road map to fly from point a to
point be what would be a reasonable altitude?

I have had a visual on highways up to 12,000 ft AGL without a problem.
Cars and lane seem to disappear as you get higher, but the ribbon
representing the highway is definitely visible

Well, fly low enough and you can use the street signs.
Seriously, if you are flying a slow aircraft, you can stay low (below
1,000 AGL). However, if it is a faster aircraft, you would probably
want to fly between 1,000 and 5,000 feet AGL. The higher you go the
easier it is to see more topographical landmarks (lakes, roads,
mountains, etc).

What area are you flying over? For the US, there is a highly accurate
add-on called USA Roads that really improves the accuracy and volume of
roads/highways across the US. It is a must for anyone looking to use
roads as a navigational tool when flying over the US.

Thanks Peter for the info I wasn't sure, when flying in the sim around my
local area I seem to loose site of even interstates at about 700 AGL. So I
guess the data is just incomplete or inaccurate.

At a FAA Safety Seminar I attended a few months ago, THE gentleman from NACO
who is responsible for aeronautical charts told us that sectionals are
scaled and drawn to be used from an optimal altitude of 9000-10,000' msl.

This framework also tends to dictate which details are included and which
are omitted from sectionals.
