I would also assume this, if I hadn’t also repeatedly witnessed the exact behaviour the OP describes. The “instant honk on green” drivers also tend to follow up with whatever reckless maneuver allows them to beat you to the next red light by 1.5 seconds. Inattentiveness and impatience are both dangerous on the road.

Where do you live that nobody drives unsafely and infrastructure can just be overhauled as soon as a problem is identified? I want to move there!
