The purpose of the NIP is to forewarn a driver who was not stopped at the time of the alleged offence that prosecution may follow, and allow the driver an opportunity to recall the circumstances and consider a defence. The rules of the NIP have been complied with, you do recall the circumstances of the alleged incident and have publicly told everybody the facts. The possible error over the road name in the NIP (not a charge or summons) is a minor admin error which has by your own admissions not prevented you from recalling events, so the Court is certain to find that there was no unfairness.
Challenge it by all means, go to Court if you feel lucky but charges and summonses can be amended particularly typos and admin so I would rate your chances as low with a risk of prosecution. We all do it, sometimes our luck runs out but Id honestly do the course if it's offered and move on.
