How’d raising gas taxes work out for Macron?

Whats the cost and ROI of police and military? Infrastructure?

Same thing.

French were paying 5x more for gas than Americans for decades and nobody was rioting.

What's happening in France is the same as what was happening here. Far right, ultra-nationalist "populism". Pissed off because your fascist darling Le Pen got beat by Macron.

Maybe there’s a limit to how much people are willing to see energy prices artificially jacked up

You have riots in the street in France over this stuff and you geniuses want to import that here

A lot of people in the U.S. really hate Trump. The Realclearpolitics average is 42%.

But Macron's approval rating is in the low 30% range, and just a few weeks ago it was even lower than that. His problems go way deeper than the"far right ultra-nationalists".

Teslas would have a hard time re-inventing their batteries to do that. Their batteries are like giant flat cell phone batteries that take up almost the entire floor-board. Makes for a great low center of gravity and handling, but replacing on a daily or 2 basis, not so much.

Those EV batteries are VERY heavy as one unit. You'd need heavy lift equipment to slide one out, and re-insert a fresh one each time. Can you imagine the stock-pile of these engine sized (or multiple ones for larger vehicles) of charged batteries needed on hand on a given day during rush hour in the AM in larger densely populated cities? You'd need a warehouse of them like you see gas stations on each corner. Watch a busy gas station for an hour and count how many cars go in and out. Imagine all those and more needing to exchange batteries? Imagine how many batteries they would need each and every day or week?

Interesting idea in concept, but on a large scale, quite a challenge to pull off efficiently.

Mass transportation on batteries in a large scale is not like charging your little cell phone.

And talk about toxic waste when the batteries lose their charge cycle efficiency. They "could" be recycled, to an extent, but many components/materials will end up in a land-fill, further polluting the environment and ground water tables.

Add millions of dead batteries and in a decade or 2 dead solar panels to the environment and you'll see what REAL pollution does to humans globally. Meanwhile we'll be waiting for the oceans to rise and force over millions of people on the coasts to flee, wondering "where is it"? rolleyes


The gas pumps we currently use aren't a first draft. They were engineered to be accurate, to shut off before overflowing and to capture vapors.

Cars could be engineered for changeable batteries, just as fueling stations could be designed to swap batteries. I'm guessing that would be easier than designing a reusable rocket that lands on its own. Besides, you've probably driven through a car wash before. Lots of heavy moving things that accommodate a variety of vehicle shapes and sizes. Also, just because you can swap a battery doesn't mean recharging isn't also an option.

I doubt something like that would happen, the battery sizes would have to be standardized across the board. But who knows, not needing a battery that goes 300 miles and or quick charging may bring the price down.

And It's not like there isn't a waste stream with current cars. Oil, transmission fluid, coolant, all recycled now but it wasn't always like that. Though an electric car still would need blinker fluid and I haven't found a single place to recycle that yet. wink

We could lower our waste generation a lot by improving efficiency.

I don't get how we aint trying to milk that tit for all it's worth.

No body has to do without.

There is more than we need.


incompetence is preferable to malice.
