Smokers are incredibly obnoxious. Smoking at a bus stop? Why not? Under open windows? Sure. On sidewalks, so that I have to breathe that stuff in when behind them? Sure.
What's that? Smoking at bus stops is banned? No problem — just move 5m away and smoke all you want, the wind carrying the smoke towards the bus stop all the same :)
And such laws are not realistically enforceable anyway.
This gets easier to answer once you consider that, unlike an alcoholic, a smoker directly harms others around him, not just himself. And that's just on top of all the indirect damage.
And then, even as for strictly the damage he does to himself, cancer is far from the only risk.
I won't comment on whether it's acceptable to speed or not. I don't think that's the point.
Most highways I drive on exhibit a predictable pattern. Slower folks in right lane. Faster folks in left lane. Maybe those slower folks are at the speed limit, or above, or below. Left lane folks somewhat faster.
Should everyone obey the speed limit? Sure! Hard to argue that point.
My observation was a Tesla driving at - let's call it "right lane speed" in the left lane. Maybe slower. Slow enough that you'd soon see a predictable back-up behind the car - some tailgating, brake usage, etc. The stuff that in my view leads to more accidents, swerving, and phantom traffic that occurs when people pile on each other, use brakes excessively, and end up slowing to a crawl.
FWIW: The "is speeding acceptable" question is somewhat resolved by police. I rarely see people pulled over for speeding within the flow of traffic, vs. somewhat swerving in/out or just driving much faster than everyone.
Don't remember the last time I saw an officer pick a car out of a normally flowing left lane to issue just that one driver a ticket.
> and at that time the prevailing wisdom was to never buy a pre-built
That's still the case, and always will be — with a pre-built you're at the very least paying for someone to assemble it for you, so it's always going to be more expensive as a baseline.
Beyond that, the chance they've chosen good components and haven't tried to screw you over on less flashy ones like the motherboard and power supply is low.
That's not to say it's literally impossible to ever find a good deal. You very well might have. Doesn't change anything though.
> with a pre-built you're at the very least paying for someone to assemble it for you, so it's always going to be more expensive as a baseline
Except isn't it possible that pre-built companies actually get better deals on hardware bought in bulk, and therefore could offset the labor costs with cheaper materials?
I believe this is exactly what's going on -- they're buying parts in bulk, often months in advance, and locking in deals that a single consumer can't easily go get on the open market right now.
Hardware pricing and availabilty pre-COVID was pretty predictable and stable, which meant the consumer could extract a meaningful cost advantage if they were willing to do the relatively modest amount of work of sourcing components individually and personally assembling the build. Right now, though, some places like Microcenter appear to have a cost advantage that fundamentally relies on market and pricing instability and can only be achieved through deeper integration with the supply chain and bulk purchasing in advance -- something a retailer like Microcenter can do, but I personally cannot.
> over 10,000 miles without intervening, including a cross-country trip.
You realize that a cross-country trip makes that achievement weaker, not stronger, right? That's just a bunch of highway driving, which is the easiest to automate and will have you racking up a lot of miles quickly.
City driving is the real test, not driving a milion miles in a straight line.
There's no way to model what a "tricky situation" may be to an opaque and ever-changing piece of self-driving software. It may fail in random ways at random times — it's completely, 100% unpredictable.
Therefore, you have to be 100% ready at all times to react in case anything that's possible happens.
Sounds way more tiring than just driving yourself and only having to account for the known, relatively easy to model human failure modes.
Trains are really unpredictable. Even in the middle of a forest two rails can appear out of nowhere, and a 1.5-mile fully loaded coal drag, heading east out of the low-sulfur mines of the PRB, will be right on your ass the next moment.
I was doing laundry in my basement, and I tripped over a metal bar that wasn't there the moment before. I looked down: "Rail? WTF?" and then I saw concrete sleepers underneath and heard the rumbling. Deafening railroad horn. I dumped my wife's pants, unfolded, and dove behind the water heater. It was a double-stacked Z train, headed east towards the fast single track of the BNSF Emporia Sub (Flint Hills). Majestic as hell: 75 mph, 6 units, distributed power: 4 ES44DC's pulling, and 2 Dash-9's pushing, all in run 8. Whole house smelled like diesel for a couple of hours!
Fact is, there is no way to discern which path a train will take, so you really have to be watchful. If only there were some way of knowing the routes trains travel; maybe some sort of marks on the ground, like twin iron bars running along the paths trains take. You could look for trains when you encounter the iron bars on the ground, and avoid these sorts of collisions. But such a measure would be extremely expensive. And how would one enforce a rule keeping the trains on those paths?
A big hole in homeland security is railway engineer screening and hijacking prevention. There is nothing to stop a rogue engineer, or an ISIS terrorist, from driving a train into the Pentagon, the White House or the Statue of Liberty, and our government has done fuck-all to prevent it.
