It’s important to note that one of these, the vehicle stability management system, is not standard on all trims; it only becomes available at SX+.
There's still some sort of traction control lower down the trim-line, no?
It's funny - my 2010 Mazda 3 GX doesn't have any traction control - that was only available in GS trims and higher. I thought the days of manufacturers making consumers pay more for baseline safety was behind us...It's not like "vehicle stability management" is some crazy suite of safety nannies or automation, after all. That sounds chintzy to me to make it standard in SX+ and higher only in 2017.
