If it's a regular (round) green light can't you go when it's clear? Or
perhaps your complaint is actually about "straight arrows"? ;-)

Nope. Through traffic has its own signal light. Left turners must
wait (interminably) for a dedicated green arrow -- even though there is
NO traffic coming at us.

It's absurd, and becoming ever-more-common here in Iowa.
