    Same here. To the point where sometimes people think I'm purposefully messing with them. I'm usually just asking for a more descriptive dialog because there's ambiguity.

    AFAIK, understeer is a condition of the vehicle, understeering is the input given by a driver to the vehicle through the steering wheel.

    How to Correct Understeer During Cornering A bit more of counter-intuitive driving. Above, we learned that added weight is not your friend while cornering. Here's another condition in which you need to fight your 'common sense' instincts https://www.wikihow.com/Correct-Understeer-During-Cornering

    A major takeaway from the above graph is that tire traction is not a linear product of tire load. Therefore, as vehicle weight increases, tire traction increases non-linearly until the tire is saturated (and the tire will slip). You can see the effects of this on another graph, below. the area between -2 and +2 degrees of slip angle is the (more-or-less) quasi-linear range of the tire's loading, and the areas that exceeds 2 degree slip angle are the saturation points for the tire. Tires are chosen so that they will operate primarily in this 'linear region', with excursions into near saturation allowed for by maneuvers. Lots to take away here. First, with an average street vehicle steering ratio of 15:1, a 90 degree turn of the steering wheel is a 6 degree steering angle to the tire. If you are cornering, and near the tire saturation point (or just past it) would you rather have an emotional and excitable human at the wheel, entering excessive and often contradicting inputs that overwhelm the system, or an electronic servo that can take measures to electronically reduce the slip gracefully back to zero.......? Next, take the case of your neighbor (it wouldn't be you, you know better who adds 200lbs of sandbags to his trunk in order to 'improve' winter traction. So he can now make it out of his driveway, just in time to become an uncontrollable missile, at the first intersection, because his tires are no longer operating in their linear region.

    A very prescient observation; you probably know where I'm headed with this then. Taking into consideration the above article, here's another piece of the puzzle.

    The 5 most common winter driving myths https://www.wheels.ca/news/the-5-most-common-winter-driving-myths/
  7. Most are very highly alkaline (the label often states not to leave on the wheels for more than 30 seconds). I switched from OEM to aftermarket pads and don't have that issue; most OEM (Audi in particular) brake pads dust like crazy due to the softer compound that provides initial 'bite'. IMO this just makes the brakes seem better tyhan they really are, as the initial bitr is too strong and then they feel soft again when you need to bear down. Try aftermarket pads; much smoother and better stopping.

    Song of the day

    Lyrics: And the angel of the lord came unto me Snatching me up from my place of slumber And took me on high and higher still Until we moved to the spaces betwixt the air itself And he brought me into a vast farmlands of our own Midwest And as we descended cries of impending doom rose from the soil One thousand nay a million voices full of fear And terror possessed me then And I begged Angel of the Lord what are these tortured screams? And the angel said unto me These are the cries of the carrots, the cries of the carrots! You see, Reverend Maynard Tomorrow is harvest day and to them it is the holocaust And I sprang from my slumber drenched in sweat Like the tears of one million terrified brothers and roared "Hear me now, I have seen the light! They have a consciousness, they have a life, they have a soul! Damn you! Let the rabbits wear glasses! Save our brothers! Can I get an amen? Can I get a hallelujah? Thank you Jesus This is necessary This is necessary Life feeds on life feeds on life feeds on life feeds on This is necessary This is necessary Life feeds on life feeds on life feeds on life This is necessary This is necessary Life feeds on life feeds on life feeds on life feeds on This is necessary This is necessary Life feeds on life feeds on life feeds on life

    The first time wasn't on purpose for me either; it was that first year that I drove during the winter on summer tires. The back end stepped out slightly, then the EBD kicked in and used the brakes to steer; it felt like driving a bulldozer, only in slow motion; strange, but fun after the scary part was over. EBD (electronic brake-force distribution) uses the ABS system to steer the car (or more appropriately, the brakes are pulsed to reduce the slip angle). It sounds a bit like the 'regular' ABS relay clatter, only a bit quieter. It feels very weird to have gone from a momentary loss of control to 'riding on rails', and it only functions below 45 MPH, but it is very useful.

    I'm very impressed with my Audi TTS's performance and handling. The first winter it arrived with summer tires, but I rode them all winter (It's doable with quattro AWD, but not a great experience). Has anyone with an Audi that has EBD tried winter drifting? you can feel the car shuffling torque around to steer you; kinda fun.

    I used to live in Crestview, and worked at Eglin AFB; the sea shells they use in their pavement are as slick as snot when wet, which adds to the excitement. I switched from most season tires to separate summer and winter tires and wheels. All seasons may be fine for three of the seasons, in a sedan, but in anything that has much performance the all season compound doesn't have enough grip. It's a compromise in the Summer (wheel hop in 4 of 6 gears), and barely adequate in the winter. Funny thing; I got used to looking at my car (with 19 inch wheels) in the summer (at first they looked cartoonishly big), but now on 18 inch winter wheels/tires they look cartoonishly small. I'm digging these for winter so far (Michelin Alpin PA4)

    Lyrics Thanks a lot, thanks a whole lot. Lulu sends her friends They cover the mouths with one hand Well, I keep waiting here Drifting around in a dark land Envelope unturned « I push the stamp and stick it » Chorus: And I know there's a bell to crack And I know there's a bell to crack Well, I hear crosstalk now Coming through the wire One voice tells me yes The other is a liar Chorus: And I know there's a bell to crack I know there's gotta be one more bell to crack « Click-clack, joint, » this thing is on my sleeve All this mess around and I gotta clean it up Okay, Mister Questions, you tell me, when are we gonna leave? And can you design a heart??a heart that doesn't bleed? Chorus: I know there's gotta be one more bell to crack I know there's gotta be one more bell to crack See the bell, so I crack it You just can't find good bells anymore! Yah! Yah! Sure! Tom Shane's a friend of mine! I really like him??he's in the industry! I know there's gotta be one more bell to crack I know there's gotta be one more bell to crack
