Do you have any other ideas?

Here's some links:

The biggest problems I see is that they do not focus on the
strength of the item the bike is being locked to.

Most parking meter poles can be cut with a portable
sawsall in a matter of minutes, and it is very cheap to
rent these tools. They can cut the head off the parking meter,
lift the bike off the pole and thow it and the meter head
(which is full of money) into a van and off they go.

Once at a shop, a compressed air cut-off wheel will
cut through a U bike lock like a knife through butter, no
matter how hardened it is.

Another trick is with people who lock bikes to the
same pole or whatever all of the time. Thieves who
cruise around, casing places, will come back late at
night, cut the pole at the base, insert a slipper inside
the pole, then replace the pole. Next day the bike
appears locked to the pole the thieves come by and
lift up the pole and snatch the bike.

Still another trick is a small oxy/acetylene torch, a
thief skilled with a cutting torch can cut through any
lock in a few minutes.

A last hazard is, of course, the government. In some
jurisdictions it's illegal to lock bikes to meters, and
the city will come along with their own locks, and lock
the bike to the pole. To get the bike free you have to
pay a ticket.

All in all your best bet is to take the bike indoors if
your not simply going to be gone inside a store for a
few minutes.
