First we see where roadname_abbrev_table (where most street suffix rules are defined) are used by: route_summary_format_bridge_tunnel, route_summary_format_order, traffic_event and direction_roadname_abbrev.

it only gets called if is_road_number is false. The function is_road_number is responsible for finding out if it's a highway name/road name and not street name. And for the moment lets assumed that it's correct.
So that is why we make sure roadname_abbrev_table has correct rule. And since the suffixes are pretty much all lowercases, we assumed that adding the 'dr' rule should work.
But since it doesn't, it might be passed with case sensitivity, so we need to add the following additional rules:

But it might not be necessary because that rule check for "dr" being the prefix (note the ^) and not suffix.
