All of this is true, and no matter how much you do it, it's still all true.
I can't even keep track of what I'm supposed to do at my own home airport that I've been to thousands of times. Some people know me on a first name basis there, and still act judgmental when something was (seemingly randomly) changed and I don't know about it.
TSA is by far the worst in the USA though. Their expectation that you do exactly what you should, without telling you what to do, while constantly changing the rules, is infuriating. Often there'll be 2-3 lines and DESPITE HAVING THE SAME SCANNERS, they'll have different unspoken rules that you are literally yelled at over.
My theory is that it's intentional; change the rules for security personnel so they don't end up in a routine, change them for travelers so... they also don't end up in a routine. If travelers with malicious intent are stressed because of the lack of predictability, they'll be extra stressed when they're up to no good.
Of course, this is baby/bathwater territory as only a fraction of a percentage of people are up to no good, and of those only a percentage is a danger to others.
i made this point earlier but in a TSA line do you not just watch the people in front of you and do what they're required to do? That works pretty well for me.
You've created problems that don't exist. They're concerns that most people don't have.
You don't know what to say. That's fine.
You might be wasting their time. That's fine.
You might not know how to end the conversation. That's fine.
It's ok to be awkward. It's ok to be honest. It's ok to bother people as long as you take their feedback appropriately. It's ok to walk away without saying anything.
The more often that you talk to people and actively reflect on the REAL outcomes of it, the sooner you'll realize those concerns aren't shared by most other people.
Well if I don't know what to say, I either don't start a conversation or I can use some opener like "How are you?" and then end the conversation (because I don't know what to say). But then what is the point?
That hasn't been the case in like 20 years. Engineering salaries are around 40K USD, although they can even stretch into the six figures for major companies with deep pockets wanting to attract elite talent. The band is pretty wide and is largely based on whether you work in a body shop consultancy (low end) or a major tech company like Google (high end).
And, like many things in this world, you'll find you'll pay for what you get.
Median salary of a reasonable developer is about 1/2th of that and if you are talking about Microsoft, Uber, Google etc., then that’s the salary of a senior dev.
But more importantly, we’re all pretending, the only cost of building anything is salaries. A company that size could blow a million dollars a month just on AWS, and the AI stuff is waaaay more expensive.
My dream has always been a toggle that switches between traditional loud sportscar exhaust and something on par with a stock BMW exhaust. Last time I checked physical switches still had a tendency to leak. The battery method could be the answer to an on-demand lower profile option.
This is super common, but the sound changes are less dependent in the exhaust and more dependent on the tuning.
In the simplest case there are exhaust cutouts that reroute the flow from a button push. Mercedes aftermarket mods are common here. But, there are also tuning changes that can be triggered in the ECU or timing changes in the valves, turbos, and other parts of the combustion flow with digital or analog input.
For instance, current EU emissions requirements keep a Ferrari F8 much quieter at idle than a 458 or 488 but it still can make the fun car sound at full throttle or with aftermarket modifications.
Look into the car you like to drive, there are many mods available, YMMV.
