It's a fun game

I finished university 4 years ago but just now I am going down the rabbit hole of bond graph modeling and studying directly from the MIT class notes of Henry M. Paynter [1] while simultaneously using Simscape at work for modeling vehicle systems. I understand that bond graphs are the underlying mechanism upon which Modelica and Simscape are built upon(?).

Can any expert in this field give me some pointers. My current belief is that understanding the theory of bond graphs will give me intuitive understanding of just about every system I work with in my field.

I find that this field is surprisingly niche, as most of my peers have never paid special attention to it, but when I found about it, it seemed to me like a magic bullet for all my problems.

So when that time comes I expect to see this mower on the frontpage again when an actual hacker does it, and then it will be much more interesting.

I read the article twice but I'm having a hard time imagining how these are supposed to work. How does showing the note to the person that is trying to get bribed differ from just telling them it's wrong and that you won't do it? Usually in those situation you don't really have a choice, like when a cop stops you in the middle of the night. Is it meant to be given in a discrete way, so that the false note is discovered after the supposed bribe?

Any plans to do this in VR? I would love to try this.

No, he died because of a steering column failure, not a loss of downforce.

Edit: I read up some more and it seems that noone really knows why he lost control. My previous impression was that the steering column broke mid-corner causing him to crash into the wall.

This is from an interview with Adrian Newey who designed the car: Newey admits that he has considered the causes of the crash repeatedly over the past 17 years. "If you look at the camera shots, especially from Michael Schumacher's following car, the car didn't understeer off the track. It oversteered which is not consistent with a steering column failure. The rear of the car stepped out and all the data suggests that happened. Ayrton then corrected that by going to 50% throttle which would be consistent with trying to reduce the rear stepping out and then, half-a-second later, he went hard on the brakes. The question then is why did the rear step out? The car bottomed much harder on that second lap which again appears to be unusual because the tyre pressure should have come up by then – which leaves you expecting that the right rear tyre probably picked up a puncture from debris on the track. If I was pushed into picking out a single most likely cause that would be it."
