Hi eggie, 
Thanks for your feedback. But this is not a way used by regular buses. This is used by parkshuttle which in an autonomous shuttle. Due to the way being 'busway' it seems some navigation systems are picking up this route to be used by cars. This is whole route is a no entry for everything except autonomous shuttles. OSM does not seem to have an path object for restricted access to autonomous/experimental shuttles. 

This causes cars / other road users driving on the path of these shuttles, which might put everyone under risk of collision. 

Would recommend this to be changed to a restricted road than a busway.

Thanks.
