Nice idea.
Have to say, I was always very map savvy, loved to overlook the route, establish what's nearby, etc.
And on the route I too would have some way points to aim for
However, SatNav..omg
Game changer.
Update of busy roads,
A refresh of route if you take a wrong turn
(A few times in map days, that was a good 5 minute session, now its done on the hoof ).
Do agree
@gennepher about missing so much around you .
One of THE beauties of the biking way, is being a part of the environment, not shut away in a cage.
But smelling the countryside around you, feeling the elements brush against you, as the bike propels you forward..(be still my beating heart )
I know You rode on bikes Genn, and I think your still a biker at heart

.
Old ways , yes if I have too.
But Skynet , if I don't .
(Hope I get the Good Arnie <pray >

)
Side note
I know many cars come with now.
(How else do they up the price and sell new improved models lol )
But why on earth anyone would choose to buy and fit a car unit, when almost any phone offers a superb offering of SatNav as OE ...

Enjoy the day all
Looks lovely here in the Capital
