drivin' along in my automobile

i was driving down a main road yesterday on the home from my doctor's appointment. for over two miles, i was stuck behind a woman in an Oldsmobile who was straddling the white line on the outside of the road! yes, she nearly struck several mailboxes and a runner along the way. she eventually got into the turning lane and as i passed her, you know i had to take a gander. she hardly looked alive and was crouched down so low that i'm not sure she could see over the speedometer. i think it's about time that we require follow-up driving tests at a certain age. for their protection...and ours! seniors aren't the only ones with driving issues, i realize that. but they're the only ones who consistently frustrate me while i'm drivin' along. i could go on and on, but i'll leave it at that.
