At least those are pointed down at the track; the reflections aren't much of a hazard. But yes, if the train rolls over you, you may incur eye damage.

It will also shoot out car windshields with pebbles and other loose objects. High-pressure air is a serious industrial safety concern.
You definitely don't enjoy books on composition or grammar.
What possible use could a Luddite feature like "delivery" have?
If done with drones, it could enrich pediatricians and veterinarians...
Any time you move the panels out of close contact with the roof, you're accepting large wind loads. That means the supporting structure -- especially if it's movable -- has to be substantially sturdier.
Well how about having the person act responsibly? No one forced any of the kids to play football
OK, so any high school kid over 18 should be free to play football.
Simple fix: Play football with the feet. There are countries where they do this.
The boxing glove did much the same thing. The human head is several pounds of thick bone, and the human hand is basically chicken drumsticks; a bare-knuckle boxer couldn't hit a man in the head very hard without breaking his fingers. The object was to hit the supraorbital ridges, opening cuts. The plentiful blood flow in the head assured that the opponent would be blinded by blood, and the fight was over. It also left him looking like the second-place winner in a knife fight, and public revulsion caused boxing bans in many jurisdictions.
The industry headed that off by inventing the boxing glove, which cut down on the lacerations. It also hardened the fist enough that a powerful man can deliver a maximum-effort blow. Result: boxing changed from a face-rearranging sport to a brain-damaging sport.
And do pilots also report to the FAA everytime they pass "within a few feet" of a bird?
Yes, if it's the kind of bird that can come through the windshield and kill you, like a goose...or the big flock of small birds that put Capt. Sullenberger's airplane in the Hudson River. Your FAA is very interested in where those birds are.
Point is, the simple presence of the drone in front of an airplane pretty well settles the issue of being "controlled"...
The Sunday sales thing is a religious law.
Was, not is. Jesus got the law on the books, but business owners took charge of it long ago. Most of them paid their legislators to overthrow it -- but there's a special class of retailers whose demand is inelastic enough that they don't need 7-day availability.
We rarely buy a bottle of liquor on impulse. It's an anticipated purchase, and we plan ahead; once in a while, if we're in a 6-day jurisdiction, we get caught without booze and we remember it next time. Sunday closing may reduce sales a little, but it reduces overhead much more, especially for a small merchant. So, at least here in Colorado, you could drink in a bar on Sunday but not buy package liquor, until we forced a change a few years back.
The same effect is even stronger with cars: we never forgo a car purchase because we can't buy it on Sunday, and Colorado still doesn't have Sunday car sales.
Do the pilots fully comprehend the fact that even though there's nobody inside the thing that it's still being controlled.
Yes, controlled into a close approach with an aircraft.
The skies are open, they are owned by nobody.
The Air Commerce Act of 1926 takes issue.
I don't mind when people state clearly that they don't really understand the absorption & radiation equations, but it does kinda piss me off when these same people pontificate as though they did.
We definitely share that hot button. Good analysis.
a radiator that reflects sunlight sounds promising for other applications, like heatsinks for space probes.
Sounds more like an oxymoron: radiation and reflection are two related but different processes. A perfect radiator reflects nothing, and a perfect reflector radiates nothing.
Parts of spacecraft that need to be cold (like infrared telescopes) are cooled by radiators that are kept pointed at dark space, with reflective shrouds that keep sunlight off them.
