Please let me know your opinion about new feature in gps software,
disabling/enabling Static Control in gps navigation,
interfering with gps receiver sensivity set by a manufacturer.

Do you think it's still safe to have third party applications to modify Sirf III sensivity in gps car navigation systems ?

Setting gps receiver sensivity against minimal velocity ?

Irrelevant. While it positively would be illegal to reprogram the sensitivity of the GPS receiver of your flight management system except with certified software and within certified limits, cars may not be navigated by instruments, and no car GPS is certified to do anything more than a paper map (or indeed a crude symbolic drawing).

It is strictly speaking illegal to operate a navigation system (or read a map) while driving, if that distracts you even slightly - if you can't handle it, you must stop to read the display. Any fool missing a road or swerving from his lane through obeying or attending to his GPS takes the full blame for any accident, no matter whether the GPS was right or wrong - and accordingly it is irrelevant whether the GPS was misconfigured or not...

I think it's fine, but how is this relevant for N810? N810 uses a crappy TI chip for GPS, and sensitivity is most likely not adjustable.

Static Control on/off feature
works the following way

while speed < 5 km/h
do
gps-fix_update = false
done

So Static Control on/off feature can be implemented into any
gps navigation system/ software/ embedded gps product.
So into N810, N800 ....

That won't do, unless you are connected to some other source of speed measurements - without a fix, you don't know your speed, so you'd never exit that mode...

Besides, a "fail on foot or in traffic jams" mode is not really desirable, decent static control would have to integrate fixes to a better average, or use other data (like motion sensors or position relative to cellular transmitters) to correct the GPS fixes.

"That won't do"
But could with a timeout

There are some software based solution for

(wikipedia)
Dead reckoning (DR) is the process of estimating one's current
position based upon a previously determined position, or fix, and
advancing that position based upon known speed, elapsed time, and
course. While traditional methods of dead reckoning are no longer
considered primary in most applications, modern inertial navigation
systems, which also depend upon dead reckoning, are very widely used. "
