Maglev Highways

[Max Rockatansky]

Wearable rocket packs will happen long before this does. Maglev technology works for trains way better than it would for cars.

There is one place where this should definitely catch on: parking lots. Those space saving robotic systems could be deployed without the cost and complexity of today's mechanical systems.

I think helicopters with grappling hooks would be more effective if that's the direction of reality we're approaching here.

Or...how about robots operating helicopters and rocket packets both equipped with grappling hooks?  Just toss some AI in and we have the seamless blend of K12/P13 future tech.

How about we get some Maglev trains first before we start talking highways. Trains are expensive enough (though very needed on several US/Canada corridors), I can't imagine the costs for Maglev highways!
