thread_title: Development history

message: There was no discussion of this prior to moving. Cat's eye is the common term in the UK and Ireland (I've never heard of a "raised pavement marker") and was where that device was originally developed.
There may be arguments for moving - if anyone believes it should be moved, please list at Wikipedia:Requested moves rather than taking unilateral action.

*I've never heard it called anything other than a cat's ete (and I've never heard either of the terms you cite).  'Raised pavement marker' sounds particularly inappropriate in British (and probably other non-U.S.) English, as a pavement is what you'd probably call a sidewalk.  And it is, after all, a British invention...  (See here for a U.S. use of 'cat's eye', though.) Mel Etitis  (Μελ Ετητης) 18:10, 20 Mar 2005 (UTC)
thread_title:  Page move 

message: In the UK cat's eyes are officially referred to as :
*"reflective road studs" Highway Code
*"stud incorporating reflectors or retroreflecting material" UK Statutory Instrument - The Traffic Signs Regulations and General Directions 2002
*"retroreflecting road studs" - BS EN 1463-1:1998 - Road marking materials - Retroreflecting road studs BSI
:That's interesting that British people use the word "studs."  Although we also use the word to mean "something that protrudes," the most common connotation of the term in the United States is a virile male horse (and in slang, virile males in general).  Thus, the British usage sounds very amusing and strange to Americans.  --Coolcaesar 19:50, 26 June 2006 (UTC)
replies: text:  Yes it is Commonwealth usage: "stud" refers generically to something that "sticks up" as it were. Example, the studs on a Lego brick and on the bottom of a pair of football boots (what US would call "cleets" I believe.) BTW we also use the word "stud" to mean any virile male mammal :) --Jquarry 00:44, 24 July 2006 (UTC)
replies: text:  While we're on the subject I'd hazard that "cat's eye" is common usage throughout the Commonwealth, certainly it is in Australia. --Jquarry 00:44, 24 July 2006 (UTC)

message: * Quick reality check - what applies in California doesn't necessarily apply everywhere else. Cat's Eye is either the official term for the British version, or as good a term as 'botts dot', besides which it's actually a different device to what you're envisaging and predates it. 82.46.180.56 21:44, 2 September 2007 (UTC)

message: I've added a photo I took of a white cat's eye to the "United Kingdom" section, since it seemed a bit odd having a Malaysian picture as the only one for what is mostly thought of as a British thing. It's not the best photo, but as I had to stand in the middle of the road to take it I wasn't keen on covering all the angles! Loganberry (Talk) 01:07, 4 April 2006 (UTC)
replies: text: Lol, that must have been fun, Cat's eyes aren't only UK, they are common in Canada on highways (most of our highways only have 2 lanes) and when I was in Costa Rica they have them there too.
* Is there any point in keeping the picture of the American yellow lines with their inferior markers on the page, it is already on the American page for their "raised pavement markers".  --jmb 21:57, 25 June 2006 (UTC)
replies: text: I concur that the picture should be removed as irrelevant to this article.  But I should note that the advantage of American raised pavement markers (particularly the popular Heenan design for Stimsonite and its descendants) is that they are simpler in design (see the KISS principle), cheaper, and easier to apply.  Yes, markers don't last very long in areas where it snows (like England and Wales), but for the large part of the planet where it doesn't snow, they work fine.  That's why so many countries are voting with their dollars for raised pavement markers!  --Coolcaesar 19:47, 26 June 2006 (UTC)

thread_title:  UK photo 

message: When ever i have watched a programme that talks about the Cat's eye it says they got their name as their inventor was walking along a clif top in the middle of a pitch black night and saw the moon's reflection in the eyes of a cat that promptly toppled over the cliff but saved his life as he knew where the cliff was. I dunno if this is just a urban legend but if it is true (and someone can find a good source), should it not be mentioned in the article? TheEnlightened 17:08, 21 July 2006 (UTC)
replies: text: In this case, the claimed story is the actual one, to a very high degree of certainty. But this needn't prevent someone else re-inventing the concept and implementing a cheaper device using recycled materials some 30 years later. TomRawlinson (talk) 11:48, 24 December 2008 (UTC)
thread_title:  How they got their name 

message: This is getting really annoying that UK editors keep inserting original research into articles about the relative merits of cat's eyes versus raised pavement markers and Botts' dots.  The disadvantage of cat's eyes as well as very similar RPMs in metal housings (obviously inspired by cat's eyes) is that the things have a bad habit of flying through windshields/windscreens and killing people!.  That's why Caltrans and most other state DOTs do not use metal at all.  Caltrans uses only plastic or ceramic markers that degrade in tandem with the epoxy, so that by the time the marker comes loose from the road, it is already crumbling into light little fragments that blow harmlessly off the edge of the road without harming anyone. --Coolcaesar (talk) 08:44, 27 February 2008 (UTC)

replies: text: Afterthought: where's the annoying original research by UK editors, please? --Old Moonraker (talk) 09:48, 27 February 2008 (UTC)
replies: text: Well, for example, this article in its current form says that Botts' dots are less durable than cat's eyes.  Although a true statement, it's deceptive and misleading in that it implies that durability is the most important aspect of a road marker.  Safety is the most important aspect.  It makes no sense to improve visibility of lanes if the markers used for that purpose can become deadly projectiles.  I suspect that part of why the projectile aspect hasn't been noticed as much in the UK is because the European Union does not have the giant tractor trailer trucks seen on U.S. and Australian roads, but that would be original research on my part to make that assertion. --Coolcaesar (talk) 07:27, 29 February 2008 (UTC)

thread_title:  Killer cat's eyes 

message: Isn't the term Ireland a bit ambiguous?
Does it include Northern Ireland there or not?
I'm sure it probably means the Republic, rather than including Northern Ireland (I can't see Britain having non-standard road markings throughout - a British Govt. nightmare), but having never been to Ireland, let alone driven on their roads I wouldn't know...
:One intrinsic problem is that the actual name of the state referred to as the "Republic of Ireland" is in fact "Ireland". So it's not surprising that Ireland crops up regularly rather than Republic of Ireland. (At least Wikipedia does not consistently erroneously refer to the Irish Republic as the BBC insist in doing through their editorial policy.
:Anyway, on this page, "Ireland" is only referred to in two places - once under the heading "Republic of Ireland" (repeating Republic of Ireland rather than Ireland would be unnecessarily laborious) and a second time in the image caption in the context "Carlow, Ireland". a) to my knowledge there is no Carlow in Northern Ireland and b) Carlow is geographically on the island of Ireland nevermind the state. zoney  ♣ talk 17:18, 22 April 2011 (UTC)
thread_title:  "Ireland" 

message: The article has incorrectly stated since 2006 that "Botts' dots (research started 1953, compulsory in California from 1966) and other raised carriageway [sic] markers perform a similar function" in the United States. It appears to have originated with this edit by now-blocked User:TomRawlinson.  It looks like he has never actually seen or driven over a Botts' dot.  In North America, reflective Stimsonite markers serve the same function as cat's eyes (i.e., creating a line of bright reflective points marking out the centerline).  Nonreflective Botts' dots preceded Stimsonite markers and merely supplement them today.  Many jurisdictions, including many California cities, use Stimsonite markers together with painted stripes, but don't use Botts' dots.  Any objections before I fix this train wreck? --Coolcaesar (talk) 13:45, 1 April 2015 (UTC)
