It's still pretty useful to know where you are and not die hitting an invisible guy wire.
Other than that, GPS is a one-way system, it does not know you exist, how fast your receiver is moving or "give" different information to one client vs another.
Even if it did, this is essentially a toy and moving slower and lower than a general aviation plane.
It uses accelerometers and other sensors because they can be sampled and integrated hundreds of times a second. The $5 gps module is 9600 baud serial and provides one update/second (or maybe 5/sec depending on which part number you pick).
The original USB mouse (for the first iMac) was round, so you couldn't orient it in your hand without looking at it constantly.
And it came with a very short cord (because there was a port on the right side of the keyboard to plug it into). But then the laptops got updated with USB ports and they were only on the LEFT side of the case.
For at least a year or two you could not buy an Apple mouse for your Apple PowerBook and use it in your right hand, because the cord was too short to go around the case.
Eventually they shipped a "Pro" mouse with revolutionary elongated shape and longer cord. (...and optical tracking, and what looked like zero buttons, which were pretty neat)
This info is in the automated weather broadcast (ATIS) audio for any towered airport.
Most large airports provide a textual version (D-ATIS), so suitably equipped pilots don't have to listen to it and scribble it down.
E.g. Heathrow now from random unofficial website: https://atis.guru/atis/EGLL

For powered flying, one a week is already on the low end... most instructors would recommend 2-3x/week.
Flying skills are very perishable, especially when first learning. This is why there are several different rules about recency of experience before you can do things like carry passengers, recurrent training requirements, etc.
Group all resolutions returned that are the same +-5% together and choose the lowest one in the desired bucket.
But we're comparing to SpaceX launches. Plenty of Raptor engines have blown up on the ground too.
There were 13 Saturn V's launched and all of them basically performed their mission (Apollo 6 being a bit of an exception) with 0 rapid unplanned disassemblies...
