I also don’t think wheel ejections were that much of a problem before the advent of hub mounted disc rotors. It happened but mostly could be attributed to user error.

The external cam skewers aren’t “cheap” in my experience. Ineffective, yes, but they are usually more expensive than internal cam skewers. And the superiority of the internal cam isn’t due to the serrations but due to the superior clamping force. Sheldon Brown has a pretty good description of why the internal cam is better. I experienced this myself with one of my daughter’s bikes that has horizontal dropouts and used an external cam lever. She couldn’t get the skewer tight enough to keep the wheel centered. We changed to an internal cam and the problem went away.

People think that the CPSC mandates lawyer lips. They don’t. Lawyer lips are probably a good idea if hub mounted discs are used with quick release but with rim brakes, they aren’t necessarily needed...if the skewer is properly tightened.
Indeed, I think we're agreeing here. I no longer have the link, but the numbers were something like a dozen or so front wheel detachment crashes per year, from both nutted and QR wheels. This was from data collected by the bike makers on warranty claims and lawsuits, before the introduction of secondary retention. With such a tiny amount of data, there was no way that they could conclusively prove that user error was the root cause, though we all have our suspicions.

Of all the things to worry about in a pack of riders seems like popping a QR would be down on the list.

I don't worry about them catching on anything while riding. Actually I don't really worry about them at all. But I have had them catch on things like bike racks and random things in the garage, you know, maneuvering the bike through tight spaces.

I've replaced the QR on a couple of bikes with Allen key skewers. On bikes with lawyer lips I find the Allen key ones quicker to install, no more trial and error to see if I got the QR tension right. I have a multitool in each patch kit so no worries there.

Man, the good riding weather must have mellowed people out. No flame wars yet.

I have no idea what you're talking about...I've been using nutted axles on all of my bikes for a very log time and never had a single problem with any of them coming loose.

Bikes have brakes. Things happen in the group. Sometimes not everyone is paying attention...they get caught out. How can you not imagine how this could happen? Use your imagination for a couple of seconds. I'm sure you've seen Tour stages or some kind of pro racing. This has nothing to do w/ what you do, obviously. Riders don't 'normally' touch wheels, but it shouldn't be a stretch to see how it they could. I've had a new racer hammer the brakes and then swerve violently in a mentoring session...that I was mentoring...after repeatedly telling this particular group to never swerve/move sideways without looking first. He clipped my front wheel and I nearly went down. I probably missed his q/r lever by a couple inches. That's how it happens.

Hasn’t touched the fork in 12,000+ miles, (nor any toes either).

This frame limits QR placement choices. But it is red!

That’s perfect placement…assuming the lever can be opened. If there’s enough space between the fork and lever to get a finger in there and pop the lever unlocked, then that’s both a well protected location to prevent accidental opening and it’s aesthetically pleasing.

I run my front skewers similarly, though crossed over the leg to the rear so that I have not only a point at which to press on the lever, but so that I have the point with maximum leverage; the end of the lever. Well protected, trim, and easy to use. Pictured is a Tune AC, the most awesome and my preferred skewers, unfortunately out of production.

Of course where the lever can go depends on the lever shape and design and the fork/frame dropout shaping, but the goal should be to keep the lever protected against accidental opening while ensuring it remains a quick— i.e. easy to use— lever.

Alberto Contador, who should need no introduction, in ‘11 with Tune ACs on the team S-Works he rode to Giro victory (overturned for drugs) and a 5th in the TdF, with Tune ACs positioned as seen here, definitely touching the fork leg (since the ACs have no cam stop).

I’m curious as to why, cxwrench , you think one should “never do that”?

This example explains exactly why you should not do that: you’ll get busted for doping.

These skewers are pretty rare and have nothing to do w/ what I'm talking about. My point is that many riders will close a skewer against a frame stay or fork leg and this will prevent the skewer from closing all the way as well as making it a pita to open.

Some do, some don't. I close one of mine lined up with my fork leg, and it does not prevent it from closing all the way.

The availability of the skewer has little to do with the point you are making. A skewer closed across the leg like that or one that is in line with the leg doesn’t have the same clamping force as a skewer that is closed in front of the leg. If aerodynamics is a concern, switch the skewer over to the other side and close it behind the leg. On the plus side, it will drive the OCD cyclists crazy

I will be altering QR lever position on my bikes, based on enlightenment from this thread. I will continue a nice flowing or tucked in front skewer position aft of the fork leg on the front, but I will move the rear lever between the seat and chain stays. Its a bit relieving to know since rules aren't well established, that makes it less likely I've been doing it wrong for the last 45 years. Never had a QR problem or an inadvertent wheel release in those 45 years.
