Idk if Tesla's claims of incorrect pedal hits are true, but I think it was pretty conclusively shown 10 years ago from the imagined Toyota acceleration fiasco that tons of people hit the wrong pedal all the time, and in the presence of an opportunistic anecdote driven media firestorm, they are more than happy to blame the car manufacturer for their mistake if given the chance.

I wrecked my first car from a wrong-pedal accident, but it wasn't because I don't know the difference between the gas and the brake, it was because my massive size 14 feet hit the accelerator when I pushed the brake pedal all the way down for an emergency stop.  E: that was part of the reason I drove manuals exclusively until I got my Leaf.

According to radio lab, the unintended acceleration can be real. I recommend listening to this episode. But if you rather not, the reason is cosmic radiation causing the unhardened car computer to screw up. https://radiolab.org/episodes/bit-flip

They let off the accelerator so quickly it's position went under zero, and since it's an unsigned int the car went into Gandhi with nukes mode.

Elviscat posted:I wrecked my first car from a wrong-pedal accident, but it wasn't because I don't know the difference between the gas and the brake I feel compelled to point out that a great many people know the difference between the accelerator and the brake pedals. But when they're panicking, they may think their foot is on a different pedal. The two pedals right next to each other, one meaning "accelerate" and the other meaning "decelerate", is a horrible user interface design, because the muscles involved in stopping are the same that are involved in going faster. In a panic situation, it's easy for even experienced drivers to be so preoccupied with what's unfolding in front of their eyes that they forget to move their foot four inches left before stomping the pedal. It's just a really, really bad design.

Nidhg00670000 posted:I'm glad you think so. Are you gonna tell us why now? Everyone already posted this, but the driver of the number of accidents that occur is not the number of people who exist, it's how much they drive. Per X VMT is a much better and more accurate normalization factor. This is also why looking at absolute collision deaths over time can be very misleading.

The US still has over 40% more fatalities per VMT than Australia, Canada and most EU countries though, so that argument isn't exactly a slam dunk.

I’m sure it’s not included in the number that Tesla guy cited, but I honestly wonder whether Tesla thinks I’m a dangerous s driver given how often my 3 absolutely shits itself when someone pulls left into a short turn lane and I physically can’t follow the travel lane to the right to continue past them soon enough to satisfy the algorithm. I guess it wants me to drive into the ditch or slow to ten mph when someone decides to turn? Anyway it’s quick and hasn’t burned me to death yet, so I’m just ignore the blaring alarms over nothing.

Fatality rate per population is also the most often presented and commonly available number. Why?quote:Defining traffic risks as the ratio of deaths to travel distances, however, almost guarantees that a statistical comparison would be invalid (and therefore discounted). The United States and Israel, for example, would seem closely similar if described by traffic deaths per 100 million vehicle-miles (1.1 v. 1.1, respectively) instead of traffic deaths per million population annually (104 v. 44, respectively). This is one reason why the World Health Organization calculates multiple indices and generally avoids the deaths per vehicle-mile statistic when evaluating traffic safety. quote:While increased VMT and higher speeds should clearly affect motor vehicle fatalities, isolating and quantifying their individual effects is empirically challenging due to the interplay between the demand for driving, traffic congestion, speeds and accidents. Cross-sectional analysis of the effect of these factors on fatalities is prone to omitted variable bias (e.g. differences in road conditions, funding, policing, underlying attitudes, etc.). Time-series analysis is complicated by reverse causality in the timing of accidents and congestion related speed reductions - that is, accidents that cause congestion, or time-varying trends in driving, accidents and fatalities (e.g. changes in vehicle technologies and safety). EDIT: KYOON GRIFFEY JR posted:I’m not arguing in favor of anything the US does in terms of road safety to be clear, I’m just arguing in favor of using actually good data and metrics. Also, you're not arguing anything at all, you might as well have said "LOL numbers bad". Nidhg00670000 fucked around with this message at 18:34 on Aug 22, 2022 |

Nidhg00670000 posted:Fatality rate per population is also the most often presented and commonly available number. Why? The thing you quoted to justify using a single metric to define relative road safety across countries says, explicitly, that it avoids single indices because traffic fatalities are complex and involve many external interactions that are impossible to quantify in a single number. Your own source says, essentially “numbers bad (when used in isolation without understanding broader context)”. YOLOsubmarine fucked around with this message at 18:44 on Aug 22, 2022 |

Steakandchips posted:American driving tests are a joke... How would you change drivers education to prevent people from driving drunk or while texting or speeding through residential areas or just generally driving like an rear end in a top hat? Do you think people are simply unaware that they aren’t supposed to do these things? You could significantly cut traffic fatalities by raising the driving age to like 20 for women and 29 for men because despite getting the same education young people (especially men) are far more likely to be involved in fatal accidents. Accidents generally aren’t cause by people lacking sufficient driving skill, they are caused by people engaging in dangerous behavior and being blind to the consequences.

It's designed around being actively hands-free (and giving you time to get your hands and feet back into position if it needs to shut off for whatever reason), and the combo of lidar and pre-scanned roads makes me way more comfortable with it than Tesla's neural net image processing guesswork. Do they actually have lidar, or is it just that the roads were pre-scanned with lidar? I thought the cars were just using radar/cameras + very accurate map data from the mapping cars.

Successfully used a charger not at my house for the first time today. Car is a Chevy Volt. Last week tried using one at a hotel - it was a Tesla branded gray electrical box with a J1772 adapter. Plugged it in but the car gave me some kind of error and it didn't charge. Today I took a closer look at a charger near my office. It's a Chargepoint charger, I had previously dismissed it because the display said something about setup not being complete, and it appeared nonfunctional. Turns out you can still use your Chargepoint account to unlock the charger and use it to charge for free, but since it's offline the Chargepoint app doesn't recognize the charging or track progress etc. Added 20 miles of range in 2.5 hours, which was a nice surprise.

Umm....not engaging in dangerous behaviour is actually all about driver skill. Part of advanced driver training is about situational awareness about dangerous behavior and that is a skill sorely lacking with almost every one of the thousands of people I taught. And it can be as simple as where is your focus when you are in traffic going the speed limit on the freeway, Imean hey thats not driving dangerously is it? The bumper ahead of you or 5 cars ahead as well? Well.. no, Because if you are focusing on the bumper ahead you are in fact not skilled and being dangerous because you are going to miss the taillights come on 5 cars ahead and lose the 2 or 3 seconds warning looking ahead gives. Thats what driver skill is actually about, not just wether you can threshold brake to try to avoid the accident you failed to see coming.

Speaking as someone who has kids getting their licence, the change in student driver requirements in Australia make an enormous difference to how well they drive. When i got my licence over 30 years ago i had had about 4 lessons and maybe driven 10 times. Today my kids had to do 120 hours before they could go for their test. You get bonuses for doing advanced driver safety courses, and also for driving 10 hours with a qualified instructor. They may still be teenagers with a worrying sense of invincibility but they are a fuckton safer driver than i was at their age.
