Hazard lights are a use case where speed is essential. If you’re on the freeway and slam on your brakes to avoid a collision, you also need your hazard lights to warn the guy behind you. Otherwise you’re likely to get rear-ended or worse. And you may have only a second to do that. I would never want to drive a car without a physical button for that function. (Unless the car is smart enough to reliably activate them itself, in which case it probably has better reflexes than me.)
