I've done the questionnaire, and here's some extra thoughts:
one of the often used appoaches to attack a lock is to hit it with a hammer or similar blunt object, sudden shocks are known to damage solid state electronics how do you intend to address this problem?
Just curious.
An alloy of Vibranium, American steel and Adamantium can cope with this exact kind of attack. I saw this in a TV show about an American guy. These are currently very much aspirational materials, but a good benchmark to aim for.
I like Hawk's idea of an elastic material or configuration to counter being pulled apart by a car jack, and could give some
flexibility when locking to larger or odd shaped objekts, although at the extremes of it's elasticity it would still be vulnerable to attack.
As most bike thieves are opportunists I think that
appearances of security can be a significant
deterent. Given enough time, space and the right tools I would imagine that all locks can be broken. However if a thief is detered from even trying that's another day that my bike stays mine, and hopefully means that my pride and joy isn't vandalised during or after a failed theft (which has happened to me before). I would not buy a lock unless in my mind it looks secure, regardless of whatever
anti-theft test standards it has passed, although this is crucial once I feel that a lock looks robust enough for me.
Equally a lock has to be
convienient enough to use when you're in a rush. Personnally I don't mind spending a few minutes securing my bike even for short periods, but I see plenty of bikes propped outside shops unlocked or with locks still in their
mounting bracket.
