[Routing] a strange routing

[Nic Roets]

Hi Vikas,

The "accurate" route makes use of the service roads that connect to the
motorways. The long route avoids the service roads.

You should consider changing those service roads to motorway_link. My
understanding is that service roads are so unimportant that they will not
even appear in most printed maps.

It looks like secondary near the starting point is duplicated and only one
of the copies is connected. That road also joins the motorway at a square
angle which is also suspect. It's much more likely that there are properly
curved on & off ramps or no connection at all.

Regards,
Nic
