Seriously wrong Car Identifications ?????????
In 2007 I was at an SAE lighting standards development meeting. Sat down next to the Chrysler delegate and asked him something or other about the lighting system on the recently-launched Dodge Matrix. Took a beat and a half before I processed what I'd said and had to go "I mean Caliber".
(I didn't beat myself up too hard about it; as far as I was concerned the Toyota Matrix and Dodge Caliber were more or less the same, and I didn't care to think much about either of them.)
