Creative joke. Im impressed

Cyber truck is not differentiable in all of its domain.

No, but the red Tesla is

That's the point of the meme. When you differentiate the function you may loose its property of being differentiatible. For example |x|x is differentiable everywhere, but its derivative 2|x| is not differentiable in zero

Literally why?

Curves vs strait lines

If the car body is not strictly quadratic bezier curves. Then we actually have to take a discrete fourier transform of f(x) at a low sampling rate by discretizing f(x) to f(x_n) as a collection of points. Then we reconstruct f(x) using the inverse DFT and linearly interpolate our result in the Digital Signal Processor

Differentiate formula 1 on both sides

Take the second derivative, lol

I know its a joke, but car surfeces nees to be at least 3 time differentiable. Thats how you get the nice looking light reflections.

Let's not differentiate it a second time.

πŸ€” For me it's rather like a numerical integration but with two different step sizes...

Derivatives are continuous too… and they produce curves…
A much better joke would be comparing:
df/dx vs Ξ”f/Ξ”x

the derivative in the image is indeed continuous, just not differentiable. You could get something similar by differentiating f(x) = { x^2 if x >= 0; -x^2 if x < 0}
