You start everyday with a full tank. You are saving 10 min every week by not filling up at the gas station. The time you save is what you spend on trips
The demand for batteries is not some fixed quantity irrespective of price.
At 130$/kWh there is demand for 300,000 units of 75 kWh batteris, may be a little more or little less. Model 3
At 160$/kWh there is demand for just 25,000 units, (Bolt)
At 200$/kWh there is demand for just 0 batteries. no one would buy it at that price
At 100$/kWh there will be demand for about 3 million units of 75 kWh a year. Tesla's projection of breakeven price between BEV and ICEV
At 80$/kWh there will be demand for something like 30 million units of 75 kWh battery packs a year or even more.
At 50$/kWh the whole world will run solar and wind. We can store two or three days electricity usage of the whole world at affordable prices.
Moore' Law for batteries, is a 7 year half life. Energy density doubles and price halves every seven years for battery packs. Right now Tesla is at 130$/kWh. In 7 years it will be at 65$/kWh. In 14 years, @ 32$/kWh we are possibly looking at the greatest disruption the energy sector has seen since the switch from whale oil to coal, from coal to petroleum.
First, Let me be the first to welcome our robotic lawn mowing overlords
The fitness landscape is constantly changing, and they are evolving. Their generation times are not long. Pretty soon they will learn to avoid robotic lawn mowers.
Just last week I saw a deer look both directions before crossing the road. Really. The only natural predator left for these rats on hooves are the the genus Automobilia species sedanis, suvis, truckis and truckis. Now they are evolving to avoid them, it is going to be impossible to contain the epidemic.
It is the price we pay for having a civil society.
My view on taxes: The Government is the largest venture capitalist. Only it has the deep pockets to invest very widely and wait for it to bear fruit. It invests in ALL the citizens, it invests in the entire country's infrastructure. It does not know who is going to hit a home run and become a super duper billionaire. It does not know which company can take advantage of the infrastructure of roads, bridges, networks and the research done in public universities. But it invests indiscriminately everywhere. It has to. It is the law. It can not prefer any one segment of the society or industry over other.
Then,... , when someone hits a home run, when some corporation earns a billion dollars and is valued at a trillion dollars,.... it comes dunning for dividend. The taxes, paid by the corporations, is not a penalty for taxes, just the dividend that rightfully belongs to the investor who made it possible.
To that snowflake dissing the public transportation, I just pointed out that he is just a little fish in a big pond. There are sharks out there. Who think exactly like him, in a very self centered way. They will eat him alive. These sharks eat lots of little fish. I have sympathy for some of them. Not for others. He falls into the category I feel no sympathy.
Hi Snowflake, We dont care about your personal needs. We don't owe you anything.
Right now big corporations make money selling you personal vehicle and convince you with billion dollar ad budgets that this is the best option for you. Things could change in a jiffy.
Public transportation is funded using tax dollars by local municipalities. They can sign unvoidable 100 year contracts. They have the authority to collect taxes to pay for their obligations. Their elections have very low turn out. If the biggies find a workable way to access the tax dollars they will drop you in a jiffy. Your personal car that works on your schedule will cost 10 times more to buy and run. If that happens, and if you are still forking over that kind of money for your notion of "freedom" then I might take you guys seriously.
We dont owe you anything. And if your personal transportation costs go through the roof, either by oil crunch, or by excessive taxation, I wont give a rats tail.
But, a point was made, black money in cash is not safe. It leads to out of control valuation of real estate and insatiable demand for gold.
But the news was not leaked ahead of time, it came as a rude shock and rattled some of the big black money sharks. They had to discount it. The sharks had to pay some 20% to 40% discount to convert old notes to new. It devalued the black money by that amount. It might nudge more honest people to use more of banking, and avoid black money transactions.
Before this move, real estate sector was always "1 crore in white 2 core in black" deals. Some honest folks are balking now in accepting suitcases full of cash. There is a small change in attitude about black money in India. But small.
The whole idea of this Aadhar system is to prevent impersonation and changing identities. In India there is no real way to find who a person is. People casually migrate across the border and melt into the society. People borrow from banks or private parties and abscond. People submit fake certificates of degrees and diplomas. Most retail stores maintain two sets of books and the owners are usually untraceable.
Indian government is making serious efforts to reduce tax evasion, and personal fraud by making cash transactions difficult. Suddenly announces denomination of large currency notes, and only people who can prove they really earned the money legally get new notes, and all the old black money notes become useless.
But there is so much corruption nothing really changes.
This ruling allows the government to collect the data. But prevents it from using it to reduce fraud.
All automakers will implement OTA. Without any push by NTHSA.
Why?
Automakers are jerks. If they realize if they can do OTA and cripple the cars after selling it and hold people or ransom they will do it. If they see OTA is a way to get steady revenue stream, they would jump all over it.
They will pitch it as safety, but once in, they will have fees every time you sell the car, to "register" the new owner, etc etc.
The right thing to demand is to have a strong, reliable OTA that is not hijackable.
So many systems now do OTA update, from Linux distributions to Windows, Android and IOS. If there is a vulnerability found in these methods, there are lot more juicier targets like banks and brokerage houses, or deep pocketed people who would pay huge ransoms. Random dude disabling the brakes of Anonymous Coward would not happen. The society would have collapsed long before that.
When consumer reports uses a very severe process to test the brakes. Five consecutive full slam 60 mph to 0 mph, with one mile of driving to "let the brakes cool" between the slams. Tesla Model 3 stopped at 130 feet in the first slam and took 160 feet in the last slam. It was declared a failure.
Tesla pushed an over the air update for its anti lock brake calibration and fixed the issue. All five slams were within 125 feet or so. Consumer Reports chief test engineer actually wrote that he has never seen such a critical component being fixed by OTA. In other vehicles it would resulted in recalls of hundreds of thousands of vehicles and still only those vehicles that were brought to the dealership would have been fixed.
Now it looks like not having an OTA is a huge mistake by the legacy car makers. They should follow Tesla and enable OTA on all their cars. NTHSA should mandate all cars should have OTA, after some cut off year like 2022 or so.
Who approved the spot welding schedule, who verified the robot did what the spec sheet demanded?
It stopped with 293 cars right? So they noticed something was wrong and fixed it in the 294th car right?
How many of these were still unsold at that point?
They determined it is a serious flaw, right?
How long did it take? How many cars were sold after that determination?

true. I did not provide energy density data. will try to dig it up. but i could be wrong on that point, too.

If your utility charges you 28 cents /kWh, why are you not using solar or wind or both?
At 130$ /kWh there is demand for 300,000 units of 75 kWh batteris, may be a little more or little less. Model 3
At 160$ /kWh there is demand for just 25,000 units, (Bolt)
At 200$ /kWh there is demand for just 0 batteries. no one would buy it at that price

Did n't they go back in BTTF VI or VII and change his name from Geroge to John?
Thanks for pointing out. They will make sure the language says, at least one male and at least one female.
If a Robert James Johnson, director, check marks F instead of M in the forms, it will meet the requirement of the law.

Read the summary. Feeling very stupid now.
Who approved the spot welding schedule, who verified the robot did what the spec sheet demanded?
It stopped with 293 cars right? So they noticed something was wrong and fixed it in the 294th car right? How many of these were still unsold at that point?
They determined it is a serious flaw, right? How long did it take? How many cars were sold after that determination?
Yeah, sure blame the code monkey.
Was very surprised and annoyed by the size of the car. How did this grow this big?
