So my phone may not yet have 5G, but my car can definitely pull 5G on its roof. Sure how many Gs one typically pulls during a car crash. 5 doesn't strike me as a lot, but of course this is specifically about force applied to the roof. I guess you have to not just roll but actually fall on top of it somehow. At any rate, some actual data would be great instead of being amazed at this marketing statement.

Weight, a force in lbs, is not the same as g-force (m/s^2), which is an acceleration. You can't directly compare the two without knowing the time over which the acceleration occurs (and even then you only get an average force over time).

The comment you’re replying to correctly used F=ma to impute the amount of sustained acceleration the roof could support.

Sorry, I don't think you're right here. Modern cars feature considerably more features (both in the bodyshell and in terms of active safety systems) which protect both passengers and pedestrians. It's simply untrue to say we reached peak safety 20 years ago and everything else has just been pointless window dressing. I buy and sell cars as a side gig, and newer cars (last 10 years or so) are far better equipped to de…

I stand my position here. While accident rates fell all across the world significantly with advance of road safety science, and active safety, no question there, but the lethality of car to car collisions has been rising, with most of rise happening in developed countries The increase in average car weight is the biggest contributor to lethality of vehicle to vehicle collision. https://www.nber.org/digest/nov11/w1717…

Your position seems to have changed - you were initially saying that safety wasn't improving, and cars of 20 years ago were safe enough. Which is patently untrue.

Now you're saying that the issue is that car weights have increased.

That's a different argument - and the links that you cite aren't making the exact point that you are - the 1000lbs/47% figure may well be true, but that's a difference over 30 years, and both papers are actually talking about inequality between colliding vehicles.

The tendency to drive SUVs is an issue, for sure, and if you're in a little car then you don't want to have an accident with a large one where there is a physical incompatibility, but like all things it has become an arms race - I wouldn't want to be in a small car of yesteryear on the roads today because everything modern is bigger - so it's no wonder that people are driving them, as no-one wants to be in the small vehicle that will come off worst in an accident.

Your last few fatalities you witnessed are tragic, but anecdotal. I've seen many situations where people have walked away from accidents that would have killed them 20 years ago - indeed a couple of weeks ago I witnessed a car get T-boned by a good vehicle on an A-road in the UK, and everyone got out and walked away - that certainly wouldn't have happened 20 or more years ago. The statistics for fatalities in the UK (the only country I have checked) don't align with your statement that lethality is rising - it isn't in the UK.

But I rarely see an analyst speak about Tesla's impressive record in building safe cars. Tesla's car safety features are not a major selling point compared to its EV features, and moreover are generally features common to EVs (i.e., additional crumple zones, floor rigidity). Tesla's autopilot still struggles to identify white trucks against a blue sky, and highway dividers, and can't seem to tell when the driver is a…

> make Teslas more likely to crash than other vehicles Citation needed. Which other vehicles? Tesla's overall safety record is quite good. Every car has things it does well and things it does badly, and every other manufacturer gets judged on the safety record on balance. I mean, do you regularly post on HN about, I dunno, Toyota's safety record given the high center of gravity of its SUV offerings that make them "mo…

Last I checked, Toyota's cars don't roll themselves over. The driver of the SUV needs to be going too fast and take a turn too sharply to cause a rollover. Indeed, Tesla Model Ys, and all SUVs, are also prone to rollover due to having a higher center of mass than a sedan. This is why anti-rollover features are now standard in SUVs: to minimize the likelihood of a rollover occuring, and then to mitigate the harm to the occupants of the vehicle in the event of a rollover.

In contrast, Teslas literally drive themselves into trucks, stopped cars, highway dividers, etc., resulting in the deaths of 7 drivers so far in a base of only a few hundred thousand vehicles, versus a rest-of-the-industry statistic of 0 across hundreds of millions of cars.

And finally, Toyota doesn't go around bragging about how its vehicles are the safest cars ever, or misstating (or even outright lying) about IIHS or NHTSA safety tests.

This is the part that gets me: The Institute’s results also demonstrate the exceptional strength of Model 3’s all-glass roof, which is supported by a very strong metal body structure and helps protect occupants in roll-over crashes. During testing, the car’s roof was able to successfully resist more than 20,000 pounds of force – that’s more than if we placed five Model 3s on top of the car’s roof at once. And, the ro…

Wondering will I ever see the day this gets fixed. Shouldn’t take more than an hour?

upvoting you for this. I thought it would break it into a block, and was wrong.

Wow, and seeing how the post appeared after submitting didn't convince you otherwise?

Well when I looked at it a bit later, I was unable to edit the original comment. Kind of makes the point moot don't you think?

I get why Tesla gets the flak from analysts, it being a public company; But I rarely see an analyst speak about Tesla's impressive record in building safe cars. Especially when there are car manufacturers who try to hide flaws which can lead to catastrophic malfunction or had been caught with cheat devices for emissions test. Also one more thing which is less talked about is Tesla's autopilot being useful for people…

This always comes up, so I am curious if one fixes for "where the Tesla is driven" when doing safety analysis? Considering how difficult it is to get a Tesla (and for older models, how expensive), surely if one fixes for location, such as suburbs and well designed metropolitan areas as well as the type of people that drive Teslas, then perhaps other vehicles will do just as well?

I am by no means saying Tesla is less safe, in fact I do believe these claims, I am just not sure if they are truly thorough.

This is hilarious to me, how this site is so badly laid out and has so many rendering bugs.

I put to doubt the utility of crash safety ratings. The survival rates for collisions on highway speeds are in single digits no matter what you do. It's just laws of physics. Modern luxury sedans have 1m+ crumple zones, and those only make for few percents extra chance at speeds above 60km/h. Extending crumple zones beyond that is self defeating, as it will only lead to further increase of average car mass, leading t…

Crash safety ratings are based on sound scientific and statistical analysis of real-world crash data and have been proven to save lives.

The process is essentially this: the IIHS looks at the most common crash scenarios which involve fatalities. They replicate the the crashes in a lab to gather data on the forces exerted on occupants during the crash. Then a test scenario is formalized and future vehicles will be scored based on the forces exerted on occupants during the crash and whether such forces are survivable.

Auto manufactures are supplied information about the tests are are given an opportunity to design their vehicles to perform well in crash testing.

Note, that the IIHS is a independent scientific organization dedicated to reducing fatalities and injuries in motor vehicle accidents and is supported by car insurance companies. These companies wouldn't be funding the IIHS if it didn't have a measurable payoff (humans are expensive to fix).

What’s with the attitude? He said he was wrong and the child comment fixed the issue. No need to castigate him.
