irregardless, the handle went into the rotor, allegedly, and paralyzed someone.
In 16 years, with almost a million bikes, there appear to be 3 reported incidents. These are mostly low end bikes so they may not be ridden a lot, so assume an average of 500 miles per year. That's 8 billion miles ridden. So in 8 billion miles, we've got 3 completely clueless people crashing, and one paralyzed.
I guaranteed you many more people than that have died riding those bikes in that time frame.
No product is perfectly safe, and its impossible to make a product idiot proof. At best you can make it idiot resistant.
I just don't find a QR lever that has been around since Tullio was a young man to be unreasonably unsafe, or a failure rate of once every 2.6 billion miles to be unacceptably high, particularly when those failures are completely the result of product misuse and totally avoidable by the proper use of the product.
And to be pedantic, irregardless is not proper usage. It's effectively a double negative; you mean regardless. [Edit, RNAV bet me to it.]
