.. sorry, but I have to agree with this view.

Not really. A lot of navigation is done in coastal waterways and
inland rivers, some of it at night or in reduced visibility.

It turns out that one of the best connected opponents to the proposed
Lightspeed service is tractor manufacturer, John Deere. Apparently a
lot of new farm tractors are equipped with precision GPS units for the
purpose of accurate seed planting and other hi tech applications.



Farmers have been using GPS guidance devices for years on their planting
and harvesting rigs. I see no reason to allow Lightspeed or anyone like
it to disrupt a service needed by many sectors of the economy.
