Interesting tidbit: The victim of last month's DWI head-on collision, on the brand-new I-485, was also a student at UNCC, and also a legal immigrant.
I came very close to this happening to me one night many years ago. A 4 lane divided highway, and here comes this driver racing the wrong way toward me. Fortunately I was able to get over to the right shoulder and stop. He stayed in the left lane while going by.
These things can come up so suddenly that it's not unusual for a driver not to be able to take evasive action. I pray for the families of the victims.
