    Kangaroos hop because they can store a lot of energy in there Achilles tendon and use that to propel them forward without using much energy. It’s good for covering long distances over flat terrain while using as little energy as possible , which is good for the Australian outback as they hop between small patches of vegitation separated by miles of desert. It’s not that good for ambushing or quickly chasing prey in a rainforest like the t rex is probably doing.

    There’s also the issue of scale, a t rex’s Achilles tendon would have to be stronger then steel cable and as stretchy as rubber to store and re use that much kinetic force from its weight.

    It will eventually have to happen, cars, including evs, are not sustainable, at least at the current levels of usage. If you look at any climate report looking into it the choice is between Americans driving a lot less or severe climate change. I hope murica will make the right choice but the more we tie cars to ideas of freedom and peace of mind the harder that choice will be. It will be tough to fight considering the tens of thousands of hours of car ads most Americans are exposed to pushing that narrative, so it will require just as much reinforcement on the negatives of cars, traffic fatalities, CO2 emissions, airborne micro plastics from tires, maintenance and repair costs, obesity, sprawled cities, etc.

    It may not happen in our lifetime, or at least when your healthy enough to bike/hike , but eventually we’ll have to transition away from personal cars. Id prefer to build towards that future now for the reasons listed above but if you want to delay that’s fine, you’ll just have to explain to your grandkids why you did.

    Yeah maybe there are are 2000 mountains, but how many have mountain bike trails? If there are trails then there is probably some organization maintaining them like the state or national park service who can also run the shuttles. Shuttles are also pretty cheap and can stop at multiple trail heads based off requests. You can also rotate where the shuttles go each day / week so if there’s a more obscure trail/mountain then you can just wait until it comes up in the schedule. The towns would also probably want to run the shuttles as well since it will bring business to the area.

    Ok, let’s assume we want less people on the mountain, what gives you the right to go to the mountain then? Because you can afford a car? That doesn’t seem fair. Also most people have a car so it’s not restricting that many people. If we say only 30 people should go to the mountain a day that’s way easier to enforce if we say only 2 shuttles of 15 are allowed. It’s also fairer as who gets to go is just determined by whoever signs up first, as opposed to whether someone owns something.

    I think many people would like to socialize. There’s a loneliness epidemic and many people are looking for friends but don’t know where to meet them. If I was looking for friends with common interests like mountain biking the shuttle up would be a great place to meet them. Just because I want to get away from civilization doesn’t mean I want to get away from socializing, I hike regularly with groups of people and they mostly enhance the experience. If you aren’t into that that’s fine too, just put on your headphones ignore everyone and set off on the trail solo, nothing stopping you from doing that.

    For the last point like I said usage can be controlled, even better then cars, but assuming the same usage a shuttle is less pollution then multiple cars. If like you said there are 5-6 cars at a particular trail head then one shuttle carrying all those people will cause less air and noise pollution and make it safer for animals.

    No I haven’t lived in rural America but most Americans haven’t either. Most live in the suburbs, cities or towns. It’s like saying people need to eat less sugar and we should stop using it for every food and people saying “what about the diabetics who need sugar” yeah they do but that’s not the majority of people. We can make exceptions for them while also overhauling our food industry to remove this thing that’s causing health problems for most people.

    As for the mountain bike scenario ideally you would take a train to a town near the trail and then the town can have a shuttle up to the mountain. If we did fully invest in public transit this wouldn’t add too much to your trip and has some other benefits.

    • This would be good for the park and wildlife in general as less traffic would make it easier for animals to migrate. Less roadkill

    • This would lower the amount of development needed in the park as parking lots wouldn’t be necessary.

    • It would make mountain biking more accessible for people who don’t have a car or can’t drive.

    • It would make it more social, you could meet people on the shuttle on the way up, if there are regulars then a community could form.

    • It would reduce the amount of air and noise pollution.

    That would work if we invested as much into public transit as into cars. This goes back to designing cities for public transit instead of cars. If we did that with the money we currently are putting into cars we could have high frequency metro lines where inner city interstate / highway routes and high speed rail for inter city interstate/highway routes along with frequent bus service in the cities/towns on the lines. We think public transit is inherently slow and unreliable but that’s because we never invest enough money to make it fast and reliable.

    1 and 2 I think have pretty good consensus. The Bering land bridge opened about 10,000 years ago while the Polynesians didn’t reach Hawaii until 900 ad, so if they got to South America it was probably after that. There is some speculation that some separate group of people crossed over even before them since evidence shows that the south American coast became populated very quickly after the Bering bridge opened. Like they got to South America before they got to the interior of north America. That could be because the Rockies are large and without the fish that those people were probably eating, or it could be that some very early people, millennium before the Polynesians domesticated coconuts, made the crossing. That theory of very far in the realm of speculation but it’s a fun theory.

    According to wikipedia this is the less likely and imo less interesting explanation. They did find coconuts that are genetically distinct from the ones the Spanish brought over from the Philippines, but those ones are more distantly related to the ones in polynesia so they probably didn’t float over. Instead they are more likely evidence of pre-columbian contact of Polynesians with south and central America, along with sweet potatoes originating in South America but being present in polynesia and SEA prior to columbus.

    So this would boot Columbus off the podium in people who discovered America.

    1. Bering strait people / native American ancestors

    2. Polynesian people

    3. Vikings, Leif Erickson

    4. Columbus


  • Depends who owns it / who payed to have it constructed. If the tenets own it and payed to have it constructed, or payed someone who payed someone… Then it’s a condo or a co-op depending on whether you own a unit in the building or own x% of the building which entitles you to a unit.

    If another organization, almost always some form of government, payed to have it constructed and owns it then it is public housing.

    If it’s anything like cities skylines original, houses just pop up according to demand with seemingly no construction cost calculated, probably because it would add a ton more complexity with mortgages and speculative markets etc. for little gain to players who mostly just want to play with trains and metros.


  • Trump said in a Truth Social post Tuesday. “Biden’s hatred of Bitcoin only helps China, Russia, and the Radical Communist Left. We want all the remaining Bitcoin to be MADE IN THE USA!!! It will help us be ENERGY DOMINANT!!!”

    Didn’t COMMUNIST China ban it mostly because it was putting strain on their grid? Not sure how wasting states worth of electricity to fuel a glorified ponzi scheme is going to help with energy dominance but who am I to question the self-proclaimed genius.
