The reason to worry about methane from cows is because that carbon started as CO2 and was converted to methane, a more potent green house gas. Methane is short lived in atmosphere, but the issue is more nuanced than just saying the cows are releasing carbon not sequestered in petroleum. Also need to consider petro based fertilizers used on the cows feed
Needs to be a little more complex. Any easy way around your measure would be to have a compromised jump box somewhere else on Target's network. POS machines send data to jump box, jump box uploads it to internet. Access to the POS VLAN needs to be tightly controlled- but then you need to pull logs of some of them, put patches and updates on them, authenticate users, after a while your VLAN has lots of holes in it.
I don't see why the model should change. The driver of the car would be liable for any accidents caused by their car. This will probably be covered by the driver's insurance. The insurance companies will only insure self driving cars that they consider safe. Insurance companies my even offer cheaper rates to cars with a better track record of self driving.
I think a slightly better analogy would be if your unlocked room is in the middle of a public store and maybe hidden behind a clothing rack. The entrance is obfuscated but there are no signs saying no entrance.
Last time I had jury duty it was for a bar fight. There was no physical evidence a fight had even occurred. It felt like a massive waste of time and made me feel foolish for taking it seriously. Not sure how often worthless cases make it to trial but it kind of changed my opinion of the whole thing.
a factor you are not considering would be how much turnout increased among black voters. This factor would not be captured in the numbers you presented. I don't know or care what the numbers are- just pointing this out.
My largest single expense is taxes. Income tax (state & federal), sales tax, property tax, capital gains tax, taxes on my cell phone service, taxes for my gasoline, meals tax at restaurants. Then there is the SS, FICA, medicaid stuff. I sure am buying a lot of civilization
Can you give me some more details? The only people I can think of who do not drive on roads are maybe people who live in cities and just use public transit? If roads are paid for with gas taxes, tolls, and property taxes people in cities will pay higher prices for the cost of goods they buy shipped in on roads (to cover the cost of gas taxes and tolls that are incurred shipping the goods into the city) or pay for roads with their local property taxes. I think roads are a pretty clear example of where people who benefit from them can pay for them with use taxes (gas taxes & tolls) & property taxes.
