I have seen far too many instances where that has happened and it has been to the detriment of the original user. That is what is happening to urban cycling infrastructure in Toronto where along with the improvements in cycling infrass tructure, they now allow electric motorcycles to use the bike lane. Or where long term gains were achieved by bow hunters only to be handed over to compound and crossbow archery hunters. For one thing you could end up with your infrastructure spaced assisted distances appart that regular cyclists can't match. Just to mention a small inconvenience.

I am very interested in electric boating. Not sure it will be what I want to see over the decades, but there the potential is vast. There are no hills on the ocean, and the winds one toys with can be avoided in areas like the doldrums that boaters have traditionally avoided. Boats can carry enough solar panels even at current technology that large yachts have gone solar round the world. Might be a little boring with neither the speed of power nor the challenge of sail. If it ever gets going there is the potential of vastly more cruisers which would reduce the freedom even today's cruiser's enjoy. But right now it is viable, and there is no reaction against techno tramps. Aux contraire, the solar pioneers are feted wherever they go. For now.

I am not sure what happened to the solar boat chronicles, but they made it a fair distance in their trimaran.

Of course all these stunt boats have limits that a true platform boat does not, as it can use whatever form of power is best, without having to concern itself with a limited form of power.
