FedEx had, as part of their safe driving guidelines, a recommendation to avoid left turns whenever possible. (In the interest of disclosure, I worked for them many years ago - early 80s to early 90s. That’s how I know this.)
It’s true that many accidents occur as a result of someone making a left turn. It’s a metaphor for politics, too!
What about left-hand turns from dedicated lanes with arrows? They’re quite safe, I’d think.
Clever observation!
I can’t tell you how many times I see some dipwad in a car trying to make a left turn across traffic with a left hand turn lane from a gas station, etc. on the corner that also has an exit on the cross street where either a left-left turn (with signal) or three quick rights could save them time. Yet they just sit there demanding a dumbass left turn.
