Yes, it was yesterday, 13 November: World Usability day 2008. This year’s theme was transportation. The Portuguese Usability Professional’s Association made it’s contribution by launching a thematic site where people can submit their impressions and experiences regarding the Portuguese Public Transport usability (or lack thereof).
One (bad) example that comes to mind are the Lisbon Subway ticket vending machines. I always get confused each time I have to recharge my travel card.
