Hello, can you please help me understand of how is the total 'maxspeed' is set to 50km/hm but it is higher for every kind of transport? (70;90). I understand that his section is withtin the city limits, but woulnd this defy logic of the Key:maxspeed wiki article? Thank you

'The maxspeed=* tag is used on ways to define the maximum legal speed limit for general traffic on a particular road, railway, or waterway. By default, values will be interpreted as kilometers per hour. The speedlimit can be specified in different units if necessary. Those will be added behind the value, separated by a space (see Examples). The tag is also used on nodes to specify maxspeed traffic signs.'
