I caught an interesting one car (I think) accident on the commute this morning. It looks like she was following too close and didn't notice brakes in front of her, tried to swerve out of the way and then wildly overcorrected. When I got even with her later she was still cruising along in the right line white knuckling it with her hazards on.

That looks a lot like the 210. I actually think the carpool lane is way more dangerous than regular lanes. I see people getting rear-ended all the time, people don't expect them to stop despite the fact that in socal they're just as congested.

Jesus, seeing video like that makes me want to go find a bare stretch of freeway and see how I react in a situation like that. I mean, I've had panic situations before and I have never, ever, come close to losing control of a car like that. Once I came over a hill at about 70 mph to much slower traffic, and I did momentarily lock up a wheel till ABS kicked in, but all I did was aim for the shoulder in case I couldn't stop in time, which I actually did. And recently a guy just dead stopped in the left lane of a 40 mph zone when he saw a fire truck coming, and because I was preparing to merge right and stop, I almost hit him. But even then I just did a fast lane change and dodged right around on my way to pulling over myself. But that holy poo poo swinging around action, I can never imagine doing that, but it's mostly because I pay god drat attention to my surroundings and watch very far down the road so I almost never have to panic stop.

Not my video (but a place I've driven a bazillion times) and kinda the same scenario: https://www.youtube.com/watch?v=9VpAY9yGaZw I wonder if everybody wouldn't just be better off if the tailgater stayed the course, braked hard, and let the ABS and the insurance companies sort out the rest. I can totally see the "anything but hitting another car" mindset in the situation though. A few good, solid, hard stops from speed would do a lot of drivers good, I think. I wouldn't be surprised if the average driver had no clue how hard you actually can brake in good conditions.

One of the things we run the kids through is full ABS stops, both in a straight line, and while making an emergency lane change. I'd say that 9 out of 10 of them do not get into the ABS until the 5th or 6th run through the scenario, even with an instructor sitting with them yelling to push the pedal harder (and having started the thing by demonstrating ABS with them riding along). I think it was Mercedes that did some sort of a study while working on their automatic braking system that determined something like 50% or more of drivers in simulated barrier collisions never used more than 80% of the braking and did not engage ABS.

I remember doing this as part of my driver's ed. It took me a few times to actually hit the ABS. Modern cars can stop very quickly indeed.

A lot of newer cars will automatically apply the brakes 100% if you go from the gas to the brake quickly, no matter how gently you press the brake. It was rather startling the first time it happened in the Panda.

The Locator posted:That seems like a recipe for rear-end collisions to me. Yeah, really. The light ahead changes, so you stab the clutch, jump off the gas, and right onto the brake, applying 20%. Then the car decides "actually, " and maxes it out? I can think of a number of situations where I'd jump from pedal to pedal quickly, without intention of braking hard.

Do you guys get to use the red/green lights that Bondurant uses? I went through that back in December (on the one day it rained of course) and I didn't have too much trouble getting into ABS... because it was locking them up pretty easy on wet rough pavement The Locator posted:That seems like a recipe for rear-end collisions to me. I've felt this kick in on my CR-V all of once. Thanks to learning to drive on my C10 with its godawful brakes, I tend to drive as if I have fuckall for stopping power (I put ~80k on a set of Hawk HPS pads and they were nowhere near worn out) but even then it can certainly be calibrated to only kick in when needed. The one time it did kick in, I'm pretty sure it helped save me from running into the guy in front of me, so there's that.

I've had mine do this a couple times, and it definitely scares you a bit. Also, got to love it when its super cold out like today and you just touch the brake pedal and almost go through the windshield. I've actually been trying to figure out the limit of my tires in the snowpack. Even standing on the brakes I can barely break these new winter tires loose.

That actually explains a lot. I was wondering why some cars offered an emergency brake priming system along with their automatic distance cruise control systems - to me it sounded like something that was needlessly being added. However, if people only really use 80% of the available braking power, I can imagine the car automatically giving you that last 20% could be the difference between a near-miss and a full collision.

ABS is used a lot more in areas that get real winters. Given how heavy vehicles have become and the fact almost no one runs winter tires, if there's any snow on the road it doesn't take much at all for ABS to start doing its thing. Now whether it helps anyone stop in that case I can't say, if your tires are completely unsuitable for conditions there's not much ABS is going to be able to do except maybe shave off a few percent of your speed before you destroy someone's rear end.

I was thinking more about my typical stop and go rush hour commute on the I-10. Thousands of cars following nose-to-tail, starting, accelerating briefly, then slowing to a stop again, with 90% of the drivers barely conscious and aware of nothing beyond the slight awareness that they should not ram into the guy in front of them. Insert a car that goes to full braking in this normal stop-n-go traffic, and it's pretty much a guarantee that someone rear-ends it.

# ? Mar 4, 2015 22:04 |

Fair enough, but at least from my limited experience with them (the CR-V is the only car I've driven at any real distance that has this ability) they don't kick in just from a quick gas-brake transition; you've got to be jumping on the pedal a decent bit already. In that case, you're really just changing who gets rear-ended first. I'd wager your old Fiesta and your Focus ST both have it.

I do my best to not do fast transitions from gas to brake, but there are at least a few times each day during the commute that someone decides they need to be in my lane right when I would normally be transitioning from gas to coast, or even while I'm accelerating, that require a judicious application of brakes straight out of acceleration. Also - I've autocrossed the Focus a few times now, and I left-foot brake a lot while autocrossing, sometimes very hard braking coming off full throttle, and I've never noticed anything, and the only times I've been in ABS where when I wanted to be.

Yeah, agreed, my point is that unless a manufacturer is royally loving up, a light tap of the brake (no matter how soon after throttle) shouldn't result in max-panic-stop. If Kozmo's really got a car that does that... that's hosed up. And in the category of fuckheads who don't know what signals mean... https://www.youtube.com/watch?v=V-QilbjSSTk (also yes I needed to clean the lens of my G1W apparently)

The Locator posted:Could be, but in that case, this description that I was replying to: An exaggeration and misinterpretation from my side, you probably have to go straight from the gas to at least 25-50% braking or something like that before it kicks in. I only ever had it kick in accidentally once or twice in the Panda. It also prevented a collision once when my ex-GF was driving and some jerkoff pulling a trailer swerved right in front of us and braked. She remarked that the Panda braked a lot harder than she expected it to, so I figure the system overrode her input and slammed the brakes. The 500 has it too, and given that a couple of AIers own 500s and probably drive them in a spirited manner, if the system was too intrusive, we'd have heard about it.

BMW does it too. I've had it happen a few times, it seems to require a very specific set of circumstances, I've never had it kick in when it was unwelcome. All that happens is the brake pedal becomes very firm with no travel at all, so your initial press causes a large amount of braking force rather than the pedal moving and gradually increasing brake pressure. It's not like the pedal feels normal but the car randomly decides to stop as hard as it can.

I'm not quite sure of the name of the system but yeah it has seen widespread adoption due to some manufacturers noticing some crashes could have been completely avoided (at least in Europe) had people not been afraid to just floor that brake pedal on their ABS equipped cars. There Emergency Brake Assist: Emergency Brake Assist posted:The first application was developed jointly by Daimler-Benz and TRW/LucasVarity. Research conducted in 1992 at the Mercedes-Benz driving simulator in Berlin revealed that more than 90% of drivers fail to brake with enough force in emergency situations.

I like the BMWs with the "panic brake light" mode where extra brake lights come on when you hit the brake pedal extra hard. It helps me realize that most modern BMW owners are idiots who leave braking until the very last second and then shove their foot through the floor instead of looking ahead. They should just replace the extra brake lights with a little flag that pops out from the fender, saying "RETARD" and accompanied with either a comedy kazoo or deflating balloon noise.

If you're real dumb and say you saw them but took no evasive action because you had the right of way. (this has happened) you may wind up being majority at fault. If you brake and attempt to avoid the accident but can't because they pulled out too close, not much you can do. Some carriers have hard ons for putting negligence on everyone for everything, and if you're in a contributory state you better have your own coverage to go through.

It's really quite clear cut, unless you hand them dash cam footage of you being stupid and going "Yee-haw" as you accelerated into him, he turned left in front of oncoming traffic. He is fully at fault here in AZ. It wouldn't even be a question as he failed to yield to oncoming traffic. If it's illegal to make a u-turn there based on the laws where you are with that pavement marking, then that makes it even more clear cut. Also, it's nice how after doing that he couldn't even figure out what lane he actually wanted to be in and ended up in the gore point.
