Anyway, even giving it my home address doesn't always help. Here
it thinks I can walk to Crystal Palace Parade, leaving at 9.27 and
arriving there at
9.10 -- that's 17 minutes *BEFORE* I left!

So what did I do wrong this time?

Nothing. It's a bug in the JP that I have reported previously in vain.
There's something seriously wrong with the walking calculations.

Maybe it assumes you're walking faster than light, thus travelling
backwards in time?

Even I don't walk that fast, and people keep complaining they can't keep
up with me...
