Wouldn't it be both? Equal and opposite forces blah blah means if a car drives in one driection then it applies the same force on the ground in opposite direction. So, the ground speed is the different between the speed of the ground in one direction and the car in another direction.

Otherwise the car would have to do some pretty unnecessary calculations to know how much force the car was putting on the earth in the opposite direction, and how much that impacted the speed of the earths rotation etc. Plus the speedo would likely have to show pretty close to 1.3 million MPH?

But calling it ground speed is not exactly right either.... GPS speed in a straight line should be pretty accurate. Most systems use more accurate positioning satellites than GPS in addition, and they all offer altitude so that can easily be factored in.

Ground speed could be off if the car is drifting for example, since the wheels will be rotating at different speeds.

Did you know VLC lets you watch videos in ASCII, and even in colour if you want? IT's pretty funny, but crazy enough I have actually had to do it for something at work once when I had only terminal access and needed to check some video!

No it's not. Working a second job at minimium wage is still minimum wage, just for more hours.

Working in a job with promotion opportunities, gaining experience and knowledge, and education help secure better paid jobs.

I recommend not running sprinklers. If you need them you probably should find something better for the environment for your garden. It's not sustainable to use sprinklers.

So, I suggest putting them away; they should not be needed during the winter normally even if you do want to use them in the summer.

The comment you replied to talked about using the waves to create a 'sonar network' that would send 'out pulses kind of like a WiFi network. So friendly ships would have access and basically have a map of the waters', suggesting a data transmittion through water, using sonar frequencies.

If they had a data transmission system in place, then they could encrypt it. If they did not then how is it similar to a WiFi network, and how would it provide a map, and gated access?
