iPad - hide the sidebar

It would be really useful if there was a way to hide the sidebar when in map view on an iPad, as you can on an iPhone. The sidebar takes up around 1/3 of the screen on my iPad Mini, and the extra space would be helpful when planning routes.

Alpe-Adria Radweg Motor-rail service & routing

The Alpe-Adria Radweg (CAAR) involves a short section on a motorrail service in order to avoid a steep mountain pass. 

Although it's marked as a cycle route, cycle.travel doesn't follow this route and sends you on a 150km diversion over the mountain pass instead:  http://cycle.travel/map/journey/46424

The motorrail is marked as a cycle route on OSM (https://www.openstreetmap.org/way/366095457#map=12/47.0308/13.1530&layers=CD), so not sure why the routing is taking such a large diversion?
