First, there are road behaviour rules, that basically disallow that.
You MUST go to crossing to cross a road here.

Second, if you want to hide sidewalks on rendering, postgis's
ST_DFullyWithin is your friend. You don't have to TAG everything you
can rather easily distinguish geometrically.

Third, try to cross these not on the crossing staying alive:
