We all do it, adding on that 5 to 10 miles per hour while driving. “Comfortably” speeding as the New Zealand Transport Agency puts it. get your attention.
Sure, when you’re at a stop sign, you do not continue until it is safe to do so. Family man here is on a straight road with unobstructed visibility and the oncoming car is impossible to miss as it’s bright silver. So, in reality he is at fault and responsible.
But fault doesn’t reverse a violent crash and speeding does reduce your available time to react to the mistakes of other drivers.
