From the viewpoint of the driver.
Interestingly enough "Bar Sinister" Like "Simon Bar Sinister" from the famous Underdog cartoon comes from the "Sinestro" Latin Root.
I think all this is true, but apparently my knowledge is of the weak and unsatisfying kind. It turns out...
"Bar Sinister" is a macaronic play on words (wordplay combining words from different languages).[citation needed] It refers to an imaginary symbol in heraldry used to denote illegitimate parentage, created by Sir Walter Scott in 1823. The term bar sinister has since been often used as a euphemism for illegitimacy. It is often confused with the bend sinister, a diagonal stripe on a shield or escutcheon."
