I have a Mazda too, I can confirm GP statement regarding lane assist... in many areas but not all: - when it works it works so well the car basically drives itself esp. when you throw cruise control into the mix (this includes auto coasting + breaking) - when it doesn't it's bouncing across the lane + applies too much resistance when attempting e.g overtaking I did not have any issue with emergency braking (never tri…

> applies too much resistance when attempting e.g overtaking It doesn't turn off when you indicate to change lanes? It does on the Hyundai.

I have a Mazda and don't have any of the issues the commenter has including any type of resistance when changing lanes.

this seems like the sort of thing that would be better measured with actual numbers, not just anecdotes from people on the internet. the NHTSA is a pretty cautious organization, and they like numbers. if they've studied it and found that automatic braking will prevent 24000 crashes and 360 deaths per year, i'd be inclined to believe them. having the car brake for me when i'm not expecting it sounds kind of scary to m…

The problem with numbers is that they don't tell the whole story. I can easily imagine a scenario where it might prevent 25000 crashes a year that are caused because 5% of drivers are staring at their phones, have a high chance of rear-ending someone, and this software makes that far less likely. While also containing bugs causing 1000 crashes a year for the larger number of non-distracted drivers, resulting in a net…

I wrote up a long comment that got scrapped by my focus filter but I feel the need to voice strong agreement here. I have a recent Mazda which in almost all ways is my perfect car except for the newfangled safety features all new cars seem to have. Lane correction and emergency braking, even set to the lowest sensitivity levels, are bad to outright dangerous in city (and some country) driving. In NYC it's common to h…

> somehow universally implemented across manufacturers... maybe. They'd need to be implemented and then turned off for 15 years until 99% of the old cars are off the road and then flipped on simultaneously for every car. If a car suddenly breaks then the car behind it better be able to suddenly break too.

The need to suddenly brake is not a new phenomenon. Cars without AEB can achieve it the old fashioned way. The driver applying the brake.

What would really save more lives would be a much stricter license system that is federaly mandated.

What little you have to do to get your license compared to European nations like Switzerland or Germany is absurd. Not only can you drive at 16 already there is basically no test to drive what is basically a tank down the road.

In the north you have the additional hazard of driving in snow and so many have no clue how to deal with it. A "Schleuderkurs" should be manditory in the north so people know what it feels like to lossee control and how to deal with it.

P.S. In Switzerland if you fail your driving test a second time you can't just do it again. You need to get a psychiatric evaluation that you are fit to drive. Yet we still have shit drivers here as well.

I am reminded of the quote, often attributed to astronaut Frank Borman: “Superior pilots use their superior judgement to avoid situations that require use of their superior skills”

There's a similar one among sailors: "The mark of a great shiphandler is never getting into situations that require great shiphandling." Anyone operating a machine in a way that doesn't leave much margin is, in fact, not skilled at operating that machine.

It's really interesting watching videos of emergency responders in my country (the UK) either showing how their advanced driving looks in practice, or in later stages of training when they're explaining their thoughts to an instructor as they work.

Their progress through traffic is markedly faster without greatly compromising safety. They aren't making violent manoeuvres, they accelerate pretty aggressively but other than speed limits they aren't breaking many rules that apply to everybody else. They are paying a lot more attention to the environment and applying excellent judgement from what they learned. For example rather than weaving through traffic like a Hollywood movie, they take clear bold lines and hold them, which gives them better vision of what's ahead and more options when things go wrong. It's doesn't look as flashy, but it's very effective.

I confess that I find a dark humor in how many self professed "great drivers" find these features a nuisance. All the while so many people are completely unaware that they have these, as they have never activated. Hard for me to square those pegs in a favorable way. Which, yes, being a great driver means you may be pushing close to limits while still be completely under control a lot. I just don't have a strong prior…

Yeah, I have to agree. Maybe I just got lucky with very capable AEB, but I've had it activate on me two or three times - and every one of those it happened basically at the same time as I smashed the brake pedal myself.

I’ve never had a bad accident in a car, but the closest I have ever come was in my friends new VW with lane assist on a dark country rode on a bend when the lane markers vanished due to wear. I started to get lazy and distracted as the car was mostly driving, my friend was talking at me and the assist disengaged, next minute we were going pretty fast towards a barrier. We recovered but it was close. I’d just prefer t…

The article cites a 38% reduction in crashes. Random anecdotes to debunk that are not super compelling. Some habitual drunk drivers never have an accident and may even claim it makes them a better driver, but that doesn’t make it the right choice on a population level.

Little hard to respond to the snark but I’m just glad I was paying attention and not on the phone or else I might be dead.

Cheers.

Huh? ABS doesn't take away my control, it improves my control by preventing conditions that would reduce traction. This system is always engaged by brake pedal input from my foot. It's not something that cars just do out of nowhere. The emergency braking system will automatically stop the car without your input whenever it wants. Judging from this thread, that could be due to anything. False positives have been repor…

> People should absolutely be able to turn this thing off if they don't trust it. Absolutely not. There are other people on the road. Families. You don’t get to kill other people in a preventable accident because you believe you’re an above-average human who can outperform a computer.

Computer errors have killed entire families.

This almost got me into a serious accident, twice. Definitely would not recommend and I switched cars because of it. The last thing I need is buggy software with the capability of instantly changing the trajectory of my vehicle (slippery surfaces, cornering). A brand car as well (MB) so really, really disappointed, what should have been a safety feature actually was the opposite. Dealer said everything was fine so th…

But they didn't study anything real world. They looked at all rear-end collisions, assumed that a percentage would be prevented and did the math to result in the 24000/360 numbers. No analysis of other affects (like sudden stops causing crashes from the cars behind them). No extrapolating from measured data.
