Here's Jimbo's test. It never fails.
Notes.
I set the software to 'running'.
1/ It takes me down Solihull By-pass, where there's NO FOOTPATH.
2/ It takes me round the M42 junction gyratory, where's there's NO FOOTPATH.
3/ It DOESN'T know there is a footpath overbridge which joins the two closed ends of the old Warwick Road.
4/ It's NOT the shortest route.
5/ If I select 'cycling' it still takes me counterclockwise round the M42 junction gyratory.
All in all, It's useless.
