Darryl Anderson was drunk behind the wheel of his Audi SUV, had his accelerator pressed to the floor and was barreling toward a car ahead of him when he snapped a photo of his speedometer. The picture showed a car in the foreground, a collision warning light on his dashboard and a speed of 141 mph (227 kph).
An instant later, he slammed into the car in the photo. The driver, Shalorna Warner, was not seriously injured but her 8-month-old son and her sister were killed instantly, authorities said. Evidence showed Anderson never braked.
Anderson, 38, was sentenced Tuesday to 17 years in prison for the May 31 crash in northern England that killed little Zackary Blades and Karlene Warner. Anderson pleaded guilty last week in Durham Crown Court to two counts of causing death by dangerous driving.
You can certainly kill someone going the maximum legal speed in a place where the speed limit is much lower. But the likelihood of injury and death still does increase with the increase in speed. So if, say, 5% of accidents involving someone going 70 are fatal, but 10% if the person is going 90 (these are made-up numbers), then if cars are not even able to go above 70, you end up saving lives.
I doubt there’s significant difference.
One of those speed limits is designed for a location where cars are unlikely to hit a human directly. Another location can have a child randomly run into the street. 70 and 170 are both death sentences.
Speed limiters in cars that don’t dynamically adjust to actual speed limits are useless and only exist to check the boxes for idiot voters disconnected from reality.
While I agree that it would certainly be ideal if a speed limiter could account for the context that the car is in, you’ve missed a lot in drawing your conclusion that it would be useless without being able to do that.
Hitting a pedestrian is not the only type of accident. If you rear end a car going 25 mph at 70mph it is not a guaranteed death sentence for all. Especially if the driver brakes, which some do not, but some will. And this is ignoring cases where there isn’t a tremendous mismatch in speed. Like, even if it reduced residential deaths by 0% but it reduced overall deaths looking at all situations, it would be a net gain with literally nothing lost. We are looking at the aggregate here. So, it isn’t relevant if you think of one specific situation where you believe 70mph isn’t better than 90mph or whatever number.
Reaction time and braking distance are affected by speed. In some cases, the person going 70 might be able to slow down enough to have the collision be non-fatal. Reaction time goes down and braking distance goes up as speed increases. If a speed limiter gives just enough time to occasionally make an accident non-fatal, then in the aggregate you have fewer fatal accidents.
In fact, taking braking distance into account, I don’t think you can even say that over the millions of miles driven, that a speed maxed at 70mph isn’t going to, occasionally, lead to a situation in a residential area where someone was able to just get out of the way in time because the car covered 30% less distance between the time the pedestrian reacted and the time the car reached that spot (or an even larger difference if the driver noticed and braked at some point as well). But again, it doesn’t matter if it’s few to none in this specific scenario, because a speed limiter of 70 will certainly reduce fatalities overall.
