The thing with registration data is if my car blows up a couple months into a one- or two-year registration, it still shows as "on the road' for a while longer.
The other thing is when they run those ads, whatever the cutoff year they use is, is where the very sharp statistical cliff begins, or they'd have picked an earlier year.
