Given that quick release levers are traditionally installed on the left
side of the bike, it seems that front disks would be better on the right
side, no? It might also slightly reduce the potential for damage when a
bike is laid down on the ground, since most people take care to do that
with the drive train upward.

But still, the lever shouldn't be able to reach the disk "spokes" as
shown in the video. Quick release levers are just a little beyond the
mechanical aptitude of some people. Bike designers (and other
engineers) really need to remember that.

A real simple fix is to reverse the QR on the front -- no need to reposition the brakes. Perhaps not stylish, but who cares. Reversing the discs front to back also wouldn't be stylish.

Laying the bike on its side typically doesn't affect the disc or caliper, at least based on my experience.

On left hand drive, right handed people think with the left brain side while our eyesight predominates brain functions....there are more eye sight nervous connections than other.

In American circle track racing, racing goes counterclockwise...if I remember the paintings, Vanderbilt Cup races were counterclockwise.

Certainly, in my van and Volvo 544 turning left is faster than turning right. I am faster left than right.

Counter steering, write experts, is done lifting bar with right hand, dropping weight....beginning with right side I assume.
Counter steering is expert

Right off, I dunno how to search for right hand left eye left brain...I was considering the electric mechanism....

Isn't the brake "on this side" at partially influenced by the force
applied by the rotating disk when the brakes are applied - depending,
of course, on which side of the fork tube the brake blocks are
located?

I don't understand your question. Care to re-phrase?

I found the file photo on this report more entertaining:

I love how the recall is about quick-release skewers but the image is of a cheap nutted axle with the hooked retaining washers.

If I understand it correctly it can only happen riding with an open QR.
Hmm...

Every bike I've ever bought in Europe has been delivered with the skewer operating lever on the right.

Of course, in a population of a million consumers, even selected by the ability afford a Trek, there will be a few eejits. This recall, like others, seems to me more a reaction to the horrendous mess the US has got itself into into by allowing liability juries to run wild than anything to do with a real danger to cylcists with their minds in gear.

All the same, it really isn't rocket science to design a lever that stops itself before it gets into moving parts, and an organization the size of Trek should take care of such details without having to be told.

I were a Trek executive, a customer turned into a paraplegic, and other notable injuries, even if less than a handful, would give me sleepless nights.

plaintiffs damage claim reads kinda borderline on fault...plaintiff lives in liberal area maybe Massachewsetts

Jay could measure off a WestLaw into RBT with the decision reasoning...

unlikely. maybe the court would bean him next time up ?

smells like 'well you cudda done that 10 other ways so why that way..
and the P's Lawyer ( who gets megapoints here) has evdiece supporting the idea...conjectural off course...that whatstheirname ? Truck ? did oit their way caws
1. it was convenient\
2. cheap
3. and Trek has sole responsibility
4. testing showed the claim was possible but Trek did it anyway.

thy should try motorcycles right ? a world beater endure !

Yes Sir, those infernal two wheel devices are Dangerous!

what we need is government intervention to prevent wheel loss....

(or perhaps a bit more accuracy in reporting "facts" :-)
