Overly Rosy?
The assessment of the 400 system seems perhaps too cheery. Some items:
 * Old bridges too low on 400?
 * In article on 400. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * very narrow shoulders on inside lane on 400, no room for breakdown in inside lane
 * Source, might be in 400 article. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * a lot of bridge abutments look pretty close
 * Source needed. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * Despite the sprawl or complexity of some interchanges, "You can't get there from here", incomplete interchanges:
 * 427 South to 401 East (have to take 409)
 * 401 East to 403
 * 403 South to QEW East
 * This is not really discussed in sources, nor generally an issue for traffic movement (aside from the 403-401-410 interchange in recent years with the westward expansion of the GTA. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * 


 * I've got a link here, I am sure it is not considered a reliable source, but I think you can see the gist of it Feldercarb (talk) 23:19, 2 January 2019 (UTC)


 * some exits are on left, say 401 to allen road.
 * Generally mentioned in individual cases, especially on 407 article. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * Several freeway to freeway interchanges feature pretty tight turns (although generally lightly used) -- "cloverstacks" -- looking at you 407/410
 * Need a source. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * weird 410 to 10 connector
 * As above. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * No overall numbering system, unlike US interstate
 * Generally not true, nor significant for an intraprovincial network. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * Interstates use even numbers for E-W routes; odd for N-S; N-S freeways generally start from low number (I5) in west and are numbered sequential. "A system". 400 series has no such ordering.
 * I think Quebec Autoroutes have a similar numbering plan Feldercarb (talk) 17:03, 31 December 2018 (UTC)


 * Wacky 403/QEW numbering (the 407 through Halton should have been 403) leaving the 403 non-contiguous
 * Discussed in both 403 and 407 articles. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * the highway from Kitchener to Guelph should have been 407, but apparently will be "new highway 7"
 * Not true. There has never been an official 400-series number for the planned twinning since its conception in the mid-1960s. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * exactly - it should "logically" be 407, but the planners have done otherwise Feldercarb (talk) 17:03, 31 December 2018 (UTC)


 * "Backwards" guidance signage - "QEW via 427" rather than "427 to QEW"
 * You need to give a reason why this is significant. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * seems backwards from what an average person might expect; eg I am looking for/expecting to get on the 427, but the sign leads with "QEW"


 * Kings Highway markers on 400 series are shown as "Crowns", but road-side markers are "Crown and shield"
 * The crown is the shield. Intersecting roads use the junction crown (the compressed one), nearby ones use a green crown with "to" above the number... at least that's what they are SUPPOSED to do according to the Ontario Traffic Manual. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * Roadside markers have a "shield" (like a coat of arms) topped with a crown. Overhead markers use just the "crown". Two styles of marker.
 * In Quebec, I believe the roadside Auto-route markers are exactly the same as the over-head markers. Why does Ontario have two different styles of marker?
 * You can see it here: Ontario has a "guide" sign (crown only) and a route marker (crown and shield). No other province has two styles, if this website is correct.


 * Wasn't the 403 touted as "death highway" for a while?
 * Yes, discussed in its article under "Controversy". -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * Carnage alley on 401
 * Mentioned in the History section of the 401 article. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * 407 was investigated by PEO prior to opening for design safety
 * Again. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * three highways had safety issue flagged, therefore "systemic" issue, bad design Feldercarb (talk) 17:03, 31 December 2018 (UTC)


 * High mast lighting on 403 on one side of the road, not down the middle, in Mississauga
 * Significance? Likely due to light pollution mitigation because the northwest side is a hydro corridor. Need a source though. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * just poor design, my opinion -- think it was cheaper to run down one side, rather than route wires under the medianFeldercarb (talk) 17:03, 31 December 2018 (UTC)


 * no lighting on some urban portions of QEW and 403 in Mississauga
 * As above. Both answers belong in the 403 article itself. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)
 * I am supposing it is a "systemic" problem in that there is no apparent standard for lighting. QEW in Oakville is lit, Mississauga is not; Toronto isFeldercarb (talk) 17:03, 31 December 2018 (UTC)


 * don't use reflectors or cat's eyes for lane markings
 * Snowplows. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * opposing centre lanes often close adjacent (no grass median) -- at night looking into oncoming headlights
 * Tall wall was designed to mitigate this, generally not a complaint, but please let me know if there are any sources on this! -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * no reflectors on 7West to 8South flyover bridge in Kitchener (oops freeways which aren't 400 series for some reason)
 * Aren't they rebuilding this? Likely temporary or unnecessary. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * might be logical to upload all freeways to province (red hill creek, the linc, gardiner, DVP), but no, we downloaded the QEW to Gardiner
 * Agreed, but only fantasy at this time. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)


 * Is the express/collector system really effective? the 407 is 12 lanes in one section without collectors
 * I'm not sure, it's based on a 1960s technique. I don't believe the proximity of the transfers and exits makes it effective in comparison to say, I-271 in Cleveland (though volumes are incomparable), but that's just a personal opinion. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)

 * I've replied in indents with my signature. I don't disagree with most points, but they are subjective and require a good source to mention on any of the highway articles. More importantly, this article is just a summary of the individual articles for each highway; most of the text is a direct copy of the respective ledes for each article. -  Floydian  τ ¢ 00:56, 11 October 2018 (UTC)

I think the idea was to indicate there are a number of "flaws" with the 400-system. — Preceding unsigned comment added by User: (talk • contribs)
 * Indeed. My reply was generally to the tune of "provide some references to backup these observations and I'll work them into the article." -  Floydian  τ ¢ 17:53, 21 November 2018 (UTC)
