The speed of sound is dependent primarily on temperature, not pressure. When the density drops low enough that fluid dynamics are no longer the primary carrier of information, plasmadynamics takes over, and the speed of sound shoots up into the tens of km/s range.

The Hyperloop concept used reduced pressure, in the hundreds of Pascals range, to reduce pumping requirements, and took advantage of that air, through the compressor, to replace expensive magnets with a cheap air cushion. This got rid of the air cushion, and the compressor, and dropped the atmosphere by an order to

Now, how long will it fire after all its water boils off?

Let’s look at the incidents...

If working collaboratively with organized crime is just “how the job gets done”, then its time to scrap the entire industry and start over from scratch.

No. Breaking is correct in this instance. It means making a sudden and unexpected maneuver, to the left, and has nothing to do with retarding motion.

The only decision they can make that would affect you is slamming on their brakes, which can be countered by moderate use of your own brakes.

Right behind a loaded semi is about one of the safest places you can be. Unless it happens to drive straight into a steel wall (it would punch right through a brick one), you’re basically guaranteed to be able to stop faster than it.

Only on Io.

Fortunately, the meat popsicle would already be dead from asphixiation.

The states with mandatory vehicle inspection also have tire renters, for renting tires to use during your inspection.

There’s still just as much flesh as always, but there’s a bit more hair...

It’s a terminal kinetic impactor. It’s traveling upwards at 3km/s, and trying to hit a reentry vehicle coming down at twice that. A solid hit at those energies means there’s nothing of significant size left. The fragments would burn up on entry. A glancing hit would still likely destabilize the RV, again causing

What stuff is there to gather? You only have two easily portable items. One is under the seat, and goes in your lap as soon as you land. One is quickly removed from the bin as you exit.

I drag my backpack out with me in one fluid motion as I’m exiting my row. There is no additional time taken.

All you’re doing is breaking the seal.

If the aluminum cage weighs as much as the steel, I’m going with the aluminum...

You are also partaking in undocumented barter. The IRS would like to talk to you about tax evasion.

On the other hand, you’re so busy fiddling with the stick, clutch, brake, and throttle (instead of just the brake) trying to downshift into that curve, that you’re unable to spot and avoid that car that’s about to sideswipe you.
