You ratchet strap it to the top of the 'long tail' and fill it with food. Duh. That tank can easily carry enough calories for a cross country trek.

>Anyone should need is the bar here?

Just because we can doesn't mean we should. Restraining technological development to preserve certain aspects of the human experience seems reasonable to me (so long as we aren't able to substantially re-engineer the human genome and change the baseline we've enjoyed for 30k + years).

Plenty of people argue that the car in general has had negative sociological effects. Not going to fight that one here as I like vehicles, but I do think that if people have to drive regularly, it wouldn't hurt to either be more in-tune with the experience or let a robot handle it entirely so that the time can be used for 'more productive purposes' (note, I doubt that people would do much with the time other than entertain themselves, but w/e). Business calls without distraction perhaps? Engage with kids during transport instead of pacifying them with devices?
