When the mother-of-two Holly Schnobrich 
became too drunken to drive, she asked her five-year-old Weston Schnobrich to be the designated driver to drive home while leaving her three-year-old Colton in the backseat lonely. Surprisingly, he was 'a good driver' and reached their home, even though he 'couldn't reach the pedals'! But the mother was arrested for child endangerment and public intoxication and jailed in Lafayetter, Indiana. Duh!
