After working with address data for the past year or so, my answer is yes please.

Address data is so incredibly difficult to work with and it's pretty clear that it's difficult for everyone involved. Census data is incorrect, OSM is often incorrect, other free sources are filled with typos, post office is consistently bad (No, my last name is not Nicholson...), shapefiles are often haphazardly done. It's so difficult to work with. That said, the amount of quality work to even get it to this point is amazing. Serious kudos to everyone who helps out here.

I've spent an asinine amount of time recently trying to get Chicago's parking ticket data cleaned up. Lake Shore drive is probably the #1 culprit:

Unique lake shore drive instances:

  $ grep "LAKE SH" tickets.csv | awk -F';' '{print $7}' | sed 's/.*LAKE/LAKE/' | sort | uniq | wc -l                                             

128

Example of the awfulness:

  LAKE SHORE DDRIVE
  LAKE SHORE DER
  LAKE SHORE DE WEST
  LAKE SHORE DIE
  LAKE SHOR EDR
  LAKE SHORE DR ''
  LAKE SHORE DR AV
  LAKE SHORE DR AVE
  LAKE SHORE DR EAST
  LAKE SHORE DREIVE
