// 1. osm id,units kmh or mph,maxspeed value
// 2. osm id,units kmh or mph,maxspeed:forward value
// 3. osm id,units kmh or mph,maxspeed:forward value,maxspeed:backward value
// There are possible examples of strings contained in the list |m_data|:
// 2343313,Metric,60
// 13243214,Imperial,60
// 3243245345,Metric,60,80
// 134243,Imperial,30,50
// 45432423,Metric,60,65534
// 53445423,Metric,60,65533
//
// Note 1. 65534 means kNoneMaxSpeed and 65533 means kWalkMaxSpeed. They are constants for
// maxspeed tag value "none" and "walk" correspondingly.
// Note 2. Saying osm id means osm id of features with OsmElement::EntityType::Way type without
// any prefixes. It's done so to simplify the debugging process. This way it's very easy knowing
// osm id to see the feature on the web.
// Note 3. A string is saved in |m_data| only if it's valid and parsed successfully
// with ParseMaxspeedTag() function. That means all macro like RU:urban or GE:rural
// are converted to an appropriate speed value and macro "none" and "walk" are converted
// to |kNoneMaxSpeed| and |kWalkMaxSpeed|.
