Bigfish............EXPECT it all the time. Have seen it plenty of times. Along with many other hazardous drivers doing various things they shouldnt be doing while driving.....at any hour of the day!!!!
I dont let it stop me from driving but I always keep it in my mind that you never know what the person in the vehicle next to might do....
I could spend hours telling you stories but I will spare you and tell you just one.....
A couple years ago heading 495 south toward the cape for a weekend of fishing... camper in tow, about midnight, no cars in sight next thing I know this guy comes screaming (and swerving between the lines...and by bewteen the lines I mean the solid ones that are separated by a few lanes

) well I was pushing 70-75MPH myself and they were coming fast.....Classic convertible Caddy doing WELL over 100mph gets to passing me and swerves into the grass....swerves back into the road misses the side of the camper by inches and only missed because I braced for the worst and headed into the rumble strips. Sleeping husband in the passenger seat wakes up and says what the F*&^ just happened???? well by the time I could speak again that car was now where to be seen! Theres no doubt in my mind that this guy didnt hit something that night. It took me a long time to stop thinking about how bad that could have been.......
