I haven't had a lot of joy with this - I appreciate it's only in
development, so hopefully you've already fixed it, but :


# The following works:
python routeAsGpx.py 51.4861044 0.3355225 51.4926519 0.3240215 car
# This doesn't:
python routeAsGpx.py 51.4861044 0.3355225 51.4929613 0.3237939 car
python routeAsGpx.py 51.4926519 0.3240215 51.4929613 0.3237939 car

These basically cover 1 mile or so of fairly simple roads.
For some reason it barfs at a section of road (the final line above)
with a footway left from point 1, and a service road off to left of
point 2, connected by an unbroken (1 segment!) primary road.

There are issues; some twit turned the service road into an un-named
residential at some point, & I've just fixed it again. The footway
doesn't have foot=yes on it (but does now).
I don't see why these should break routing past them? The major road is
a long unbroken way which the first example copes with nicely.
