You're not alone. I tend to say away from lane mapping 'cause I think it's
going to do my head in.

Bike lanes are not counted. The wiki page
https://wiki.openstreetmap.org/wiki/Key:lanes is fairly clear.  Parking
lanes get tagged with the parking:lane key

I had a go at tagging the northbound:

and southbound:

Needs a review because you can guarantee that you'll make a mistake if you
tag something then point everyone on the mail list at it ;-)

Also this isn't the only way to tag it, I could have used the vehicle:lanes
tag rather than the access:lanes tag to get the same outcome.

You can see how hard it would be to programmatically check if the number of
*:lanes is consistent with the lanes=* tag
