Hmm, could you elaborate a bit on your concerns? Put another way, what's the worst that could happen?.
Also, it seems to be GPLv3 licensed https://github.com/soyjavi/tuktuk#licensing-options with a special commercial license for OEM's. I don't know how exactly that works - i.e. their methods of detecting OEM users and definition thereof (hence, without knowing these things, I see where problems could come about, but how likely are they to?)
" Not to mention you have to mind wind conditions..."
I can calculate the vector angle, wind considered, to almost 0.99% accuracy. Zero dot nine nine, my friend. While driving on the freeway.
"...otherwise the drop might land at someone standing/sitting/moving near by."
But then there's no reason to spit in the first place, is there?
I do it. I think it sort of gives me a sense of comfort. But it seems to run in the family - on my father's side. My dad shakes his leg. As do my brother and yours truly. My paternal grandfather is a leg-shaking champion. I can't say for sure, as he is dead, but I'm pretty sure my paternal grandfather's father would out-leg-shake us all combined.
And then, on my mother's side, nobody I can think of does it. My mother hates leg-shaking. I try to be decent about it when she's in the room. Fortunately, my wife - who doesn't approve of legshaking, and seldom shakes a leg - doesn't really give me grief about it. Guess she's written me off as a leg-shaker, and accepted it as one of "those" things.
Whaat? I had a stint in college studying Mechanical Engineering. You have to basically chain yourself to a desk and become an actual recluse-hermit mutant creature if you want to get through.
I'd say that's pretty 'special' - in a certain context.
I swear, I was shaking my legs when I read this. I'm a "software engineer" - you didn't specify which type of engineer.
I just had to comment because it felt like you were talking to me; like in some of those weird movies - "You! Yes, you - there's no one else in the room. YOU, the one leg-shaking. Listen up..." - kinda thing
