“Law and order” = “rules for thee and not for me”

This is nearly copypasta worthy

Front-facing radar is the bare minimum needed to pass the test given (fake-road wall). Many vehicles use it for adaptive cruise control, and radar is even faster than either cameras or lidar for figuring out the range to an object. 1000 Hz measuring distance to an object is enough to find both the relative velocity and the acceleration of another object. This provides enough time to apply the brakes safely when approaching a vehicle or obstacle

LIDAR is even better, and also more compute intensive and expensive to install.

I think Tesla was very short-sighted in removing radar sensors, certainly. If they hadn’t, they could’ve spent more of their energy on making the FSD cars better instead of just making them sufficiently safe with insufficient sensors

That’s definitely part of it. Also not an expert, but I believe you have the gist of it. Diesel engines are more efficient for a couple of reasons, not the least of which is more efficient heat capture to use for Work.

Another factor would be that if you want to do an oil combustion into steam power, you have a few issues:

1. You now have to lug around a LOT of both fuel and water, instead of just water and dry coal. Water and oil are both heavy by comparison to coal when lugging a train car of it around.
2. you now have two areas for heat loss to happen. Steam engines require massive boilers, high heat, and run much greater worst case failure risks (I.e. explosions) which are at highest risk when the water runs out. Coal is worse for this than I imagine oil would be, though inertia is a powerful force. Why move to another complicated system that does the same thing when you can use the old one?
3. Supply lines and training: if coal is already managed logistically, why switch to something else that provides a marginal benefit when coal is both cheap, easily accessed, and your engineers already know how to use it?

I’m sure there are even better reasons out there, but that’s what comes off the top of my head.

Something something .dev

I feel your pain man. Our university of 40k people did the same thing “from on high” and we ran into the same problems in our lab. We only had 4 million files to move into a Teams share. Which, btw, takes about 5 weeks to “sync” to OneDrive, which is how we were expected to replace our workflow instead of a shared network storage drive our lab owned

In this context, yes, because of the cancellation on the fractions when you recover.

1/3 x 3 = 1

I would say without the context, there is an infinitesimal difference. The approximation solution above essentially ignores the problem which is more of a functional flaw in base 10 than a real number theory issue
