Crossings?  Interesting.  I've been taking a bit of an interest in them as you may have seen.  Just trying to tidy them up a bit, but there's so bloody many!  I went through and removed a whole heap that various people had added to driveways.  I mean, if you need an alert coming out of your garage not to run people over.  You probably shouldn't be driving!  Definitely a lot more needs tidying, but I think I need a macro or something I can monitor, as it's hard on the hands doing them over and over.  Even just better defaults would be a start.
