I was thinking the same thing. I was disappointed that Car Play was not ready for my GLA's delivery but now I have the Command stuff that talks to my iPhone even when it's in my pocket, and I can even call out to Siri if it's sitting on my centre console ("Hey Siri..." etc.), I'm not sure what more I would need. I guess if you're crazy enough to want to Tweet as you drive, you might find it useful in the short time you have before you get distracted all the way to hospital, but given that the Command unit will even read out the news to me while I'm driving, I'm not now sure what else I could want!
