Relevant: http://www.quora.com/Why-haven-t-cars-yet-solved-the-problem... Apparently most people set up their mirrors incorrectly by overlapping view paths, when it would in fact be better if things moved between mirrors without any overlap (e.g. rear view mirror covers the back whilst the side mirrors cover blind spots - no overlap in between). I've tried it out and it feels rather weird, but I must say I've found i…

I have had my side view mirrors setup like this for years and it isn't always better. The first problem is that you cannot see your car in the side view mirror. This doesn't seem like a big deal, but it can be difficult to judge where everything in the mirror is positioned if you don't have a reference point. You get used to this. The second issue is that if you have a big straight long line of cars behind that are c…

I already had a side mirror that eliminates blind spot a few years ago on my Peugeot 207 (I live in Europe) although it didn't have such an angle of vision. Even though it's a neat invention, I still have to vomit every time I read the word "patent". And to say crooks are working hard to bring these to Europe

There have been patents in Europe for quite some time now.

Yeah, I was talking about idea patents.

Being able to patent an actual implementation is somewhat ok, but being able to patent ideas is plain stupid, and they are in the prrocess of importing it to the EU

Why do you have blind spots in the first place?

http://www.caranddriver.com/features/how-to-adjust-your-mirr...

"The paper advocates adjusting the mirrors so far outward that the viewing angle of the side mirrors just overlaps that of the cabin’s rearview mirror." I've been driving this way for a long time, and it's great. You can already see behind you: you don't need 2 more mirrors showing you the same thing.

Blogspam. Original press release from Drexel University: http://www.drexel.edu/now/news-media/releases/archive/2012/J... Added value in PhysOrg article: zero. Please, everyone, stop submitting links from PhysOrg and ScienceDaily . I have never ever ever seen anything on those sites that isn't either (1) bullshit or (2) a recycled press release with zero (or often negative) added value. (Sometimes it's both at once.)…

Is there a good aggregator for that sort of stories that does add value?

(I don't visit either site, but an aggregator with that focus might be worth visiting).

I think you are a little harsh in bashing the sources. Their value is that they serve as a distribution of press releases from many sources. That is exactly how a press release is supposed to be used. And I can go to a press-release redistribution site and see press releases from various organizations in a related field instead of having to check each organization individually. Yes, please filter the bullshit. But su…

While I agree that the sites are useful, HN guidelines request that you submit the original article. That reduces the number of duplicate submissions.

There are no non-"idea" patents. By their very nature, patents are there to provide a monopoly on novel ideas. If I come up with the design for a new gearing system and patent it, then you have an idea for a substantially similar system and build it, you're violating my patent. It's all about ideas.

Not sure why this is news. They've existed in Europe for over a decade. i've had them on my VW Golf almost since I bought it (Mirrors: http://www.ecstuning.com/Volkswagen-Golf_VI--TDI/Exterior/Mi...) they're convex, and variable radius. They're great. MUCH better than the "Car and Driver" technique. The problem is, as usual, regulator - DOT requires carmakers to sell new cars with a flat drivers side mirror.

Curved mirrors are more efficient in one sense but tends to lead people to misjudge distances. Presumably the government think that showing a misleading picture may be worse than not showing one at all, which is not complete idiocy. This mirror apparently doesn't really suffer from that problem, but the legislation didn't anticipate it - which isn't really surprising, it's hardly realistic to expect them to foresee t…

Any mirror tends to lead people to misjudge distances and speeds. Mirrors are not things we naturally understand and you have to get used to judging how far behind you something is, while looking in front of you. If you're looking in a mirror and something comes in your direction very fast, you tend to step back... directly into the thing coming at you. Curved mirrors also take getting used to, but I doubt it has eve…
