I have never understood the stealth-issue. I can see why you would want a small cam so it does not impair your view, but why is it important to hide the cam from other roadusers?
Some moron wants to throw out the rule book & use the wrong (but empty) lane to jump a queue then overtake you on a roundabout.
There is a prang. Said moron jumps out & starts accusing you of dangerous and erratic driving. He also refuses to hand over his details.
Said moron is also about half your age, a good 6" taller than you and looks like he 'can handle himself'.
Said moron then tells a bunch of lies to his bosses & their insurance company. There was an implication that I was speeding & driving erratically. He also said I hit him (his vehicle) on purpose and that I was extremely irate. He also had half a dozen witnesses to back up his story (not one of them appears anywhere on the video!).
I wonder. If I was using some huge camera that stood out like a sore thumb, would said moron have been bothered? Would he have taken advantage of his youth, size and physique to help himself to my camera ? In this day and age, people have been stabbed simply for looking at someone 'in a funny way'.
After all, his lie and the sudden appearance of half a dozen witnesses add so much weight to his argument that, even with stills from the camera, my insurance wanted more evidence.
The way I dealt with this was to remain calm - knowing I have a most reliable witness, distract the idiot by moving away from my vehicle so that, aside from his initial 'attack' where he got out & walked towards me, my vehicle was always behind him and simply repeat that the insurance will sort everything.
Of course, I could be 100% wrong. The idiot might have seen the camera and decided it was pointless to argue since everything was recorded - but I very much doubt it, guilty people can do the stupidest things if they think it will get them out of trouble.
In any event, our insurance contacted us in January to say that the other party had finally admitted fault. Which seems to imply that despite the overwhelming evidence of video footage, the other party can hold up proceedings by claiming non fault etc?
That is why I insist on the stealthiest setup I can find.
Edit. Just occurred to me. There's a large number of YT clips from countries where they just love the bright & blingy cameras fixed to their screens. Despite this, they still show clips of morons walking out & deliberately jumping on their bonnet - one guy headbutts the screen so much his head bleeds and the screen crazes. If people will do these stupid things with an obvious camera, why would another motorist back off when they see your cam (even though the chances of them spotting it at normal road speeds etc etc would be fairly remote).
