Ah that is actually pretty cool (and does indeed seem to make little robots nearly useless).

I would expect it is still could be useful, unless the sensors allow to pinpoint the target area within a few meters ? Otherwise you have to start digging up the whole pipe section that is covered by a sensor ? Or am i missing something obvious ?

I am wondering how easy is it to spot cracks in pipes on camera images from the inside ? If there is a cm wide gap I suppose it is visible, but small cracks ? Especially if there is dirt in the pipe ?

I can hear pigeons walking over the roof of my flat even after trying to sound proof it with 10cm of mineral wool. I would be really interested in hothey dealt with the sound/vibrations of the windmills. Reserve the top floors for deaf ppl ?

Yeah, but in 'buying format' i have selected 'all listings' so i assume it should appear (i dont have a 'classified add' type to select for some reason as i read in some help tutorial). And if I enter a direct url to the item (using the ID) i would also expect it to pop up and not say the item is not found. Can you see the item ? (not that i have a cool spare 1.6mil , but i am interested in looking at the pics)

Anyone find the ebay link ? I get nothing, even if i put the item id visible in the screenshots (2184409783) in the url it says it does not exist.

Mmmm I don't have a need to hear my machine, if they were not so bloody expensive and have limited range I would have an electric one actually :). If you feel this kind of audio feedback gives you more driving pleasure, would having artificial engine sounds in the speakers of eg your helmet or in ear headphones be a substitute for the real thing (can't be that hard to generate sounds based on your actual drive behavior so it feels realistic, and you could have different parameters to make the sound configurable to whatever mood you are in that day) ? So far I never felt unsafe because of the lack of engine noise, but I did notice that cars don't hear me when I lane split at red lights so I am stuck behind them. Solvable by revving a bit more. But if there is another loud motorcycle with me they make place immediately :), so I (partially) agree with that point. I actually once had a car backing into me, during one of my first moto drivers lessons but luckily my instructor saw it and honked which solved that problem. I am in Europe though, so maybe that is related why I less have the feeling cars are trying to kill me if I don't make a lot of noise ( So far I was never in the US so no idea what it is like there). The motorcycle bans are pretty "popular" in Germany now eg https://www.visordown.com/news/industry/thousands-german-motorcyclists-demonstrate-against-riding-bans. And I understand those people too (in favor of the bans), because you might pass in 5 seconds, but one minute later the next one is there already and you don't have a moment of rest. But as a motorcycle owner I also want to do those roads of course (I have a campervan in which I can fit the motorcycle so I have driven everywhere in Europe). Mine is a honda nc750x, so not really something terribly impressive and sexy I am afraid, but I like it. Anyway, safe travels !

As someone with a (rather silent) motorcycle myself I see your sentiment a lot and I 100 pct don't get it. It's like the apartment neighbor that per se wants to play loud music annoying everyone around them. Why do you want to be that neighbor that everybody hates ? A desperate need to be in the center of attention when you pass somewhere , even if it is negative attention ? There is a small safety aspect to loudness if you are lane splitting, but I do not feel that is a justified reason to constantly annoy everyone around you, and I can rev a bit to make more noise if the need arises. Also loud motorcycles are causing more and more bans on nice roads for ALL motorcycles because ppl are just fed up with it.
