Am I the only one here who doesn't understand adults collecting Hot Wheels?S

No offense to anyone who collects them but I just don't understand. Hot Wheels, Majorettes and other similar die cast models were great as a kid and I have quite healthy collection of my own that I do not plan on departing from as they have sentimental value. My dads vintage matchboxes are also cool. I understand collecting accurate scale models and owning bunch of Matchboxes from childhood but why buy inaccurate Hot Wheels when you can buy more accurate scale model for little more money?

Please enlighten me
