Meanwhile in 'merica, we have the Apocalypse Hellfire (actual name!)...

I'm relieved to see that the Mad Max future we were promised is still on track. :)
I've been preparing for Valhalla, shiny and chrome!
You aren't truly free if you don't have the ability to burn a gallon of gas for every mile you drive and run over cyclists like a kid stomping on ants.

This reminds me of the Call of Duty Black Ops edition Jeep on the road the other day. Felt completely surreal.
Who tf paying 6 figures for jeep with a raised bed?
Uh, yeah, well, um, shut up!
At this rate, the Chinese are just dunking on us.
Any day now, they'll successfully teleport someone like Star Trek.
What is the price and efficiency of these vs maglev trains? As I understand, maglevs can already surpass 400kph.
I just kind of assumed that it was a maglev.
No, highspeed trains are tradition trains using wheels. They just go really fast but start to hit a hard cap around 400kph where wind resistance becomes so great that it becomes harder and harder to overcome. Maglevs on the other hand are far more efficient at extreme speeds. Maglevs can get up to like 500+kph now.
Makes sense, I guess maglevs need whole new infrastructure build for them too which takes some time.
Wouldn't air resistance pose a similar problem for wheeled trains and maglev? Or is it the air resistance of the wheels and supporting structure itself that creates the difference?
I think it's easier to design maglevs to be more aerodynamic but also the lack of needing wheels at all is a big deal. Basically high speed rails are far more efficient at lower speeds but require far more energy at high speeds specifically because of the limitations of wheels and friction based propulsion.
Maglevs are far less efficient at low speeds due to the energy requirements of the magnetic levitation, but at high speeds beat out the rails because they just glide over the tracks and are propelled by fucking magic and no moving parts.
This is how I understand it. Deepseek told me. lol
It looks sick
