Lake Shore Drive

This one seems odd...just noticed it in my RSS feeds.

Something tells me that 90 isn't the actual speed limit for Lake Shore Drive in Chicago.

90 km/hr = 56 mi/hr

That might be the speed in kilometers. If you change it to mph, say 55, put in "55 mph" in the maxspeed= * tag.

It seems someone is confusing mph and km/h. OSM uses metric units so the data states that the speed limit is 90 km/h.

It is most common in the states to use mph so it shoud say "55 mph".

The other thing is if its 55 MPH it should be 88.514 km/h, implicitly OSM uses metric units so 90 would be 90 km/h. Like the others I'd use
maxspeed=55 mph
