We're looking at thousands, if not tens of thousands, of miles that will require overhead or 3rd rail electrification.
It can be done, but I'd estimate 20 years or better...plus government subsidies
The longer we wait the less work there will be to electrify the rail lines. We have already eliminated 2/3 of rail lines in the US, in favor of jackknifed semis on I-95. From ports to deliveries to freeways to airports, we have seen the failure of the US transportation infrastructure.

Since I was a kid riding in the backseat of a car, I wondered why the median of the US highways wasn't utilized.

Seemed like a perfectly good place for a monorail when I reading about them in other countries. Of course, I didn't know what a lobbyist was at age 10 either.

No. I believe we are working towards new tech battery storage with solar also high tech generators that charge off train motion.
You know you just have to think it and with whats possibly coming it will happen.

Example: you dont like the color of your car.... change it with a app.
BMW has developed a wrap for cars that with electrical input will change from black to white with all shades in between. What's next? color?
Remember the same question for television in the early 1950's

Now we're raising the question "Why?" There's a big difference between a TV, which for most purposes is stationary; and an automobile which costs (at least) ten times more. All of this "new and exciting stuff" is great, yet adds more to the price and doesn't make a vehicle go one inch further before it's ready for the junkyard. Then again I've never understood why somebody would pay 70k for a pickup or SUV, when 40% of that cost is for bells and whistles. To me, the main purpose of an auto is to get from point A to point B as inexpensively as possible. I've always owned pickups because I have something in the bed about 90% of the time; and a car won't survive the roads I drive. (Especially at the speeds which I sometimes travel them. :D) I'm still waiting to hear how well a Tesla will handle 10 ply tires...

I think your missing how camp mode works, coupled with the best case seceniro at every turn for your little hot take to be correct.

If a battery is only charged to 80%, and the battery shuts down camp mode at 20%...you have 60% of usable battery, in the cold, to get you through a scenario that lasted more than the car was designed to handle.

I don't think I missed a thing...
But it only uses about 14% for one 9 hour camp session. 60%\14% = 4 sessions = 36 hours. One of us is still missing something.

How to use camp mode in your Tesla​

When you invested in your Tesla electric vehicle did you ever imagine you’d be sleeping in it? If your idea of glamping involves putting down the seats, adding a mattress and some pillows and putting the vehicle into “camp mode,” then the Tesla is the place to be! We explore how to use camp mode in your Tesla and why you might want to check it out!

Whether you’re going to “off-road” at a campground, camping in your backyard or taking a cross-country road trip in your electric vehicle, Tesla’s Camp Mode makes it infinitely more comfortable.
We have a guide to a camping trip in your Tesla Model 3 or another Tesla model. Because we aren’t certain whether coronavirus will allow for airline travel or if you’re not certain you want to stay in a hotel, we have a guide to camping in your Tesla and using Camp Mode.

Charge your Tesla up and go

Many RV parks today offer the option to charge most electric vehicles, letting you charge while camping under the stars. Charge overnight then set off on your road trip the following day. There are also many places at which you can charge your electric vehicle for free.
Tesla introduced the new “Camp Mode” feature in December 2019. To camp in your Tesla, fold down the rear seats, add a mattress and camp out! Earlier iterations of the Tesla didn’t provide an option of being able to keep climate control and the lights on for long periods when the vehicle is in park mode; thus Camp Mode was introduced by Tesla.

What exactly is Tesla’s Camp Mode?

The Camp Mode feature lets you to turn your vehicle into a comfortable and breathable car and one in which you can — in theory — comfortably sleep and camp in.
When you put your vehicle into Camp Mode the cabin will maintain its interior lighting, temperature, airflow and play your music, once you’ve enabled Camp Mode.

How do you enable Camp Mode?

On the Tesla’s touch screen, touch the fan icon at the bottom of it, then touch the icon marked, “camp.” Keep in mind that the vehicle has to be in Park mode to use the Camp Mode option.

Are there times Camp Mode cannot be used?

  • It cannot be used unless the vehicle is in Park.
  • You need more than a 15% charge remaining. A thread on Twitter noted, though, that Camp Mode could be used even if the battery charge was as low as 5%. We haven’t tested that yet, though.

Energy consumption

Running the vehicle in Camp Mode will eat up about 10% of the charge in an eight-hour time frame. If it’s extremely cold or otherwise inclement weather, the battery will be drained more quickly, simply because it will have to work harder to maintain the interior temperature you’ve chosen. Even at low temperatures for about eight hours, you’re looking at a consumption of around 15% — not bad. Keep in mind that these are averages and estimates — don’t leave yourself without enough charge to get to a charging station.

Unexpected “camping”

Imagine you’re unexpectedly stuck in a snowstorm or if your vehicle — is for some reason — stationary and you can put it in park and hang out. A Tesla owner in Norway, Bjorn Nyland, wanted to see if he could live in his Tesla so he decided to camp on a road that had closed due to snowfall. He wanted to see how much battery the Tesla would use when in Park and in Camp Mode. This was a test, but imagine if you were stranded on the highway for several hours and had to survive in your vehicle until the road opened or help arrived — this is good-to-know news.

Nyland, an influential Tesla evangelist uses Camp Mode to see how well his vehicle performs in the frigid, snowy temps in Norway. He camped for twenty-four hours in temperatures at (14°F/-10°C) and the charge in his Tesla Model 3 went from a full charge to around 50% charge in those chilling temps.
Performance in a frigid snowstorm drained about 2 kWh per hour. You could conserve energy by turning off the touch screen.

Camp Mode: Do you need it?

As with any technology there seem to be dissenters. Some Tesla owners, on the Tesla Motor Club site, deemed Camp Mode “useless” and offered an alternative:
  1. Turn off the vehicle’s lights
  2. Set the desired temperature to Keep Climate On
  3. Turn on the rear vents. They need to be turned on as they won’t turn on automatically
  4. Disable/turn off the Walkaway Door Locks option
  5. Turn off the vehicle’s dome lights and Sentry
  6. Finally, turn off the Alarm (it’s under the Safety and Security option)
If you open the driver’s door you will need to go through all the steps again in manual, not Camp Mode. Use the app on your phone to lock the doors and the screen will turn off.

^^^^^
That sounds just like what I would do if stranded in my pickup; run the heater sparingly and wrap up in the blanket which is supposed to be in my emergency kit. The difference is that I would get out occasionally to ensure that my tailpipe wasn't blocked. (Assuming that I was stuck in a snowstorm.)

In reality though, part of my winter emergency plan is to keep my snowsled in back of the truck. If that won't get me out, I waited to long and the snow is too deep. Then I'll just build a snow cave and wait for spring. ;)

Some things some get wrong about EVs by mistake or by intent perhaps.

Hopefully this may be of interest to some, illustrated by the charts.

Why the switch to EV? Pollution and migration away from oil dependency.
The world's largest producer of oil is the US, followed by Saudi Arabia and Russia.
ICEV requires fossil fuel to operate, while EV requires batteries to operate...but wait...batteries must be charged to operate.
So how is electricity generated? 60.6% is generated by fossil fuels.
Batteries: where do the materials come from to make the batteries?
Well, China by a wide margin, 80% (the US is ranked #15).
What country pollutes the most? China.

The bottom line is switching from ICEV to EV is accomplishing what? Instead of oil running the vehicles it's running the generators that make the electricity that charge the batteries primarily made in China...the world's largest polluter. Then some argue photovoltaics are the answer...free sun power. But again today nearly half the world's photovoltaics are manufactured in China.
Am I alone in seeing this? What am I missing?
I believe many people aren't seeing the big picture and understanding all of this as well as increased power consumption means power grid upgrades which that cost is passed on to the consumer.
