There may be a biosecurity issue. We can't have people just bringing in weed, with the concomitant risk of Mexican Marijuana Maggots devastating our local crop.
Well, Russia refrained from trying to infiltrate Austria (and after the 1950s, NATO refrained from trying to infiltrate the Warsaw Pact - before that they did, but all their attempts were betrayed by Philby).
But then, Khrushchev and Brezhnev (not to mention Eisenhower and Nixon) were relatively sane and responsible politicians.
True. But actually, I'd incline to the view that Europe would be more secure if the Baltics and Poland were neutral and secure by treaty (like Austria after 1955) and there was a demilitarised buffer between Russian and NATO forces.
The rush by NATO to move its frontiers up to and beyond the limits of the former Soviet Union does not seem, in retrospect, to have been sensible realpolitik.
USA has never been invaded
Also, Japanese forces occupied the furthermost Aleutian Islands in WW2: https://en.wikipedia.org/wiki/Aleutian_Islands_Campaign.
What's the worst that could happen?
China and the US face off, the yuan becomes non-convertible, exports to China dry up, mortgage funding follows, Auckland house prices drop by 80%, all the banks crash under the weight of bad debts, people can no longer get paid or buy food.
It's a well known problem. I've written algorithms that attempt to solve it without doing a full Dijkstra walk through the road network for each location pair.
You can take them inside, if it isn't jammed with cruise ship tourists off to do the "look at a town with water next to it from quite high up" for the 19th time on their fun-packed holiday.
I'm fairly sure that Hitler actually escaped from Germany, and via Argentina, moved to Springfield, where he murdered Marge Simpson and tried (with some success) to pin the blame on OJ. Also he's Barts dad.
Well, no. My current car costs maybe 40c a km to operate. A real taxi is $3-4. Plus, I can taxi into the city easily enough, but suppose I want to go out to the Rimutakas and go hiking - it'll cost a fortune and getting a ride back is going to be an issue. For most people, anything with a human driver is not going to be an economic alternative to owning a car.
Fast forward a few years and I get a shiny new autonomous car. It costs me more, maybe $2 a km. If I'm using it in town, I'll need to pay either parking or a few extra kms for it to drive out on its own to someplace with free parks.
Or I can send it off to earn a living - or use somebody else's car. Reducing the cost, maybe by half.
The problem is the puke factor. What percentage of passengers will mess up cars? If they do, the car goes off to be cleaned and enforcement robots pop around to the miscreants residence for a cup of tea and their kneecaps.
I don't think the point is replacing human driven taxis by manual ones for taxi journeys.
It's more that:
- a huge number of people currently own a car
- self-driving cars will eventually happen
- if I take my self-driving car into town, I probably won't leave it in a park while I'm there, I'll want to send it home, or to somewhere I don't have to pay for parking
- or I could have it earn money transporting somebody else
- or I don't own a car at all, and just send for one when I need it
The latter is what Uber want to own - not all the people riding in taxis, but all the people riding in their own cars.
