Sorry, I'm used to VHF/UHF voice operation on 2-meter - a.004 difference isn't all that bad and would still be entirely functional - the service/band that I'm talking about is not channelized.
LEO is a lot faster than the crusing speed of a 757. The doppler shift involved is almost completely negligible.
Assuming the plane is moving directly away from you (maximal doppler shift) at 858km/h (typical cruise speed), with a wave speed of 'c' - you have a doppler shift of +/- 3.974975 kHz.
Clapper and Alexander have those new fancy "truth inverters" installed. When they deny something, it's true. When they admit something, it's not true - and if they refuse comment... hide.
Wrong. Around here, it's either 45, 50, 55, 60, 65, or 70 - depending on what county you happen to be in at the moment.
Oh not to mention those random spots where it drops from say 65 to 45 and back (or down to 35!!!) for no conceivable reason. Better not miss that (one) sign!
2 seconds!? Do you have a disease or disability? I can sit with a stopwatch (yes, so I'm already multitasking with that) and I can get useful information while only having my eyes diverted for1/2 of a second typically - sometimes shorter if I only need to catch the shape of something (eg the turn direction indicator)
It's more dangerous to reach over and adjust the stereo volume!
Also, at 70mph, you better not be anywhere near houses. 50 feet (1/2 second) is peanuts compared to stopping or maneuvering distance. If something happens close enough that that matters, you're going to roll your car avoiding it or hit it anyway while (ineffectually) stopping.
I have seen high speed chases where the driver was executing maneuvers in such a way... he/she clearly was not only in charge of all their faculties, but calm.
Seriously - we're talking about multiple spin recoveries (after PIT maneuver attempts) in a row. Car started to spin, they spun into it and completely around and kept on going - didn't even veer off course.
Eventually it was a mechanical failure that stopped the chase - one of the tires finally had enough and blew.
This has always bugged me. There are some stretches of highway/roads where you don't see another sign for miles, and if you just turned onto it you've no hope at all. To make matters worse, some counties around here set different "default" limits so you can't even make a safe guess on context!
Speed limit signs should be posted at every entrance to the road and major intersection. They don't need to be prominent - perhaps even only visible to those entering/turning onto said road.
Autofocus? I didn't realize we had bionic eyes yet. Maybe I'm special or you're defective, but I don't have any problems switching focus between near and far when something is masking/overlayed over my vision. Hell I can do it with either eye with equal ease!
I can't stand the voice prompting, and it always gets turned off immediatly. I don't need to be told a dozen times to keep right, I surmised that by the fact that I'm turning right in 2 miles and all the road signs indicate the exit for this is on the right. I don't stare at the GPS either, a quick glance is all that is needed - and my field of vision is wide enough that I can still see the road ahead of me when I do so (albeit not with the same detail of course)
Just because it CAN be displaying something completely irrelevant doesn't mean it is. I feel the same way about phones - prove it before you write the ticket. Pulling them over for a warning/check is entirely fine, but don't write that damn ticket unless you know.
I don't need my GPS, but I use it all the time. Why? Because it gives me a relatively accurate ETA, and if I have to deviate off course, it immediately adapts to this - where I might otherwise get completely lost. Sure, I'm smart enough to be able to figure out which relative direction I'm moving in, but that won't tell me that the neighborhood I'm driving through doesn't connect to the road I expect to be on the other side.

Now THAT is interesting!

More context: so the plane would be going, perhaps, 1000km/h (or 0.277km/s). Orbital velocity for LEO is 7.8 to 6.9 km/s.
In short, that was what I would call a stupid question.

I'm pretty sure radios capable of transmission are still a no-no.
I'm pretty sure they have all known about this for some time. This isn't a new thing.

Wait! Can we have them play in traffic first?
... and I hope that "string of profanity" was directed at the NSA who put it there.

Indeed. My speedometer has matched every roadside radar display I've encountered.
If they wanted to do such things it would be far easier for them to plant trackers surreptitiously - not fired noisily while tailgating the target.

I don't need my glasses for driving either, so you're saying I should take them off because they "obstruct" my view?

Oh, really?
How does that disagree with what I said? That sounds exactly like an amalgamation of anonymous people from all over the place.
Which doesn't make any sense in this context, given that EA is both the development house and the publisher.
... and now they get none of it (from me.)
Are you stupid, or have you just been living under a rock?
That does make sense for digital distribution, but in that case it's a copout for building infrastructure to handle the distribution.
However, in this case it's merely a case of continuing the tradition commonly seen with physical distribution (which attracts the same scorn).
