There's one old lady down the street who drives a big Cadillac...She can barely see over the steering wheel, hugs the curb if another car is coming toward her, pulls over to the wrong side of the road to access her mailbox. (Rule of thumb: if you can't walk out to your mailbox, you probably shouldn't be driving a car.)
Whenever I see that Caddy coming toward me, I prepare to hop up and over the curb.
I'm lucky to have a much younger and assertive wife. She'll make me stop driving when it's time.
