I was one of the folks on the ground getting things fixed. I had 600 car dealerships stretching from Texas to Guam and 60 pieces of software to get updated.

Bonus - Because of the '00 model year cars coming out before the calendar year change, it all had to be done early.

I explained the problem like this:

Imagine if the US decided to come out with a new quarter, and it's super cool, but it will not work in any coin slot currently in use.

If you have the know how, and the proper tools, changing the coin slots at your business or apartment building is not that big a deal.

Changing ALL the coin slots on your block, in your city, or in your country? Suddenly a much, much bigger deal.

Even with all the work we put in, there were still problems. A DMV in the NE started issuing vehicle registrations for '00 "Horseless Carriages". There was a cab company in Thailand whose meters rolled over to Midnight and suddenly thought it was noon.

But most likely you never heard of any real problems because we all worked our asses off.
