I don't understand PDC either. Yeah, and it's an eyesore +1
PDC is for old men who forgot their glasses, or anyone who doesn't have a feel for driving their own car. Which I can't understand. I like gadgets, but some are just overkill IMO!
To each his own though, I guess! I won't make fun of anyone who orders it. At least not to his/her face....
I hope BMW does not make PDC mandatory on M-DCT cars like they did with SMG.... uhoh......
