I think this is misunderstood - everybody points out that how evil BMW is for trying to be proprietary, then immediately points out any Chinese factory can produce a compatible tool for pennies - which one is it?

I think this is a pretty good mechanical design in general because:

- large contact surface (like hex or torx)

- no chance of slide-out (like flathead) or torque-out (like Philips)

- you can use a different size screw bit than the screw, and it wont slide around, or destroy your nut like torx does with hex

The article says it cannot withstand the torque of torx or hex.

Torx and hex already solve the slide out problem.

Which part of this makes you think "Hmmm yes this is great design"? What would bad design look like to you?
