Presumably, if these were mass-produced, each device would have a rare or unique signal similar to car remotes.

> Also as far as I can tell this lock relies on the poles/posts being of a certain diameter

I thought of that too. There are standard light pole sizes, but they might be different in different countries. I wonder if it would work s well on wooden posts.

I think the bigger issue would be how would your bike descend with another bike under it?

Same issue as "what happens if someone locks their bike next to mine and they are dumb enough to put their lock through my bike".

You'd have to assume that anyone who double parks on the same post with a lock like this probably isn't smart enough to ride the bike in the first place.

The actual question should be "what happens when there are too many people using these locks so no-one can find any places to use it?"

Such thinking is exactly the sort that is guaranteed to end up with your bike stuck up a lamp post due to a double parking incident ;)

(it doesn't quite fit, but the spirit of "Foolproof systems do not take into account the ingenuity of fools" applies)

Your bike would still be stuck up the pole until they removed their double parked bike.

Sorry, I misunderstood. I thought he was saying the other person would use his remote to steal your bike.
