Back in the day, I could recognize the make, model, and approximate year of most cars on the road, at least the ones from 1940-1970. I knew, for example, how to tell the difference between a '55 and '56 Chevy, or a '59 and a '60. I could spot a car a quarter mile away and know it was a '51 Hudson or a '56 Ford Vicky. Now, with a few exceptions (PT Cruiser, Subaru Forester, VW Beetle) they kind of all look the same. I can't tell a Toyota from a Chevy without looking for the logo. I'd like to think this is due to change in the way cars are designed, and not to my getting old.
