Here's one of my favorites from my desktop support days. A frequent flying calls in one day to report that her keyboard is broken. Diagnostic questions indicate that it keeps entering spaces all on its own.
I bring a replacement but first sit town and test-drive it without any issue, to her surprise. Next, I watch her type. Now, this user happens to be a rather large woman, working at a somewhat cramped desk. After typing for a bit, she exclaims, "See, it's doing it again!" Sure enough, spaces are appearing in her word processor, and her thumbs are not pushing the spacebar. Her breasts, however, are. I delicately explained to her that she is "leaning" on the keyboard. By rearranging her desk and seat, the problem was happily solved.
Unfortunately it takes long enough to reproduce and is unreliable enough that I'm not willing to do enough trials relying on just engine-braking that I would be able to draw any firm conclusions. I have tried relying on gearing and I suspect it has something to do with the brakes but I don't know.
The last stretch where it goes down to 40 and then 30 is steep enough that engine braking without any brake pressure at all is not going to happen safely. And there are lights too, I almost always (but not always) hit at least a couple of them coming into town, so stopping is kind of mandatory there (and unpredictable).
I don't have a habit of riding the brakes though, I'm either gently depressing them or my foot is off. But without gearing down there's going to be a significant amount of intermittent braking; just not continuous.
I purposely brake intermittently. But, the brakes are definitely very hot when I've checked them.
I had wheel bearing issues with a previous older car, under similar circumstances. I checked steering, it doesn't seem to make much difference. The dealership dismissed wheel bearings as a possibility and said they checked the CV joint.
Their only theory the first time around was a small rock or something getting stuck in there and working its way out. The old "mud in your tires" sort of thing I guess (Joe Pesci reference). That's a mighty devilish rock.
I have this problem. When I drive home after a long commute, I have really, really loud wheel noise (loud like impossible to ignore, turning your head on the street kind of noise). This only happens when I am driving 40 minutes or more, and only on the last couple miles to my house (which happens to be several miles of downhill driving with a fairly steep grade towards the end). The noise continues to persist, even at very low speeds once I get into town. If I let the car sit for just five minutes or so, the noise goes away.
This doesn't happen every time I drive home. It might depend on environmental conditions. It won't ever happen if I just go for a quick drive up and down the hill. The dealership has not been able to find anything wrong with it or come up with any explanation. This has been happening for over two years, it's a 2013 Honda hybrid, bought new. I've speculated if it could some brake-related issue that only manifests when braking regeneration is suppressed when the battery is full. Has me at my wit's end. When I get home from work the dealership is closed, and even if I could make it into the dealership with the thing clanking away, by the time I could get in and talk to someone the noise would go away unless I had them on the phone and ready to hop into the car at a moment's notice. So much for the warranty.
Is there a freaking link to the videos Gatto and Galchenko did of the five-club five-up 360s in a minute? All I find is this and a couple of other articles describing them, but no links. And it doesn't seem to be on Gatto's current channel.
Edit: I love how Gatto's record-break is just buried in a practice video. Very Gatto of him.
