I don't understand why are you removing `bridge=*` without modifying `man_made=bridge` either

Please don't remove un-divided carraigeways mapped as `change:lanes=`

The only correction you need to edit in is add `junction=roundabout` to the ones without

Please don't use `oneway=yes`. This is not a correct style. `railway:preferred_direction=` is used.

Allow me to explain that `junction=roundabout` on a line means it makes up a roundabout only. It doesn't represent a single roundabout. Some other data representation would be used for collecting a single junction. This avoids breaking routes.

Again, merging roundabout breaks bus routes.

Please don't merge roundabout sections for no reason. This breaks bus routes.

Please don't split physically non-separated roads

`crossing=` `=marked` or `=unmarked` also doesn't make sense when there are multiple kinds of markings.

Please don't scramble `crossing=traffic_signals` values

Heung Yuen Wai hasn't fully opened, and the editing on PRC's side has been messy.

They are obviously not similar, as Heung Yuen Wai and Lok Ma Chau can be accssed by non-Expressway roads. Plus, I'm not the one that edited them.

Please don't draw individual lines for mini-roundabouts. They don't have physical separation.

This has been discussed many times. `noref=yes` is used here together with `highway=trunk`.
