Mercedes-Benz says Level 3 self-driving option ready to roll

The effect is huge. Energy goes up quadratically, so here (4->9) you have more than doubling. Stopping distance goes up quadratically (well, due to reaction time there is a linear component in there as well, but still).

And if there is a sudden obstacle that you can just avoid hitting going 20mph initially, you'd hit it with 22 mph if you're going 30 mph initially (assuming no reaction time and constant deceleration).

I submit that that's a massive difference: hitting a child not at all or with 22 mph.

Things can be quantifiably described as "doubled" without that having any real world impact.

In my experience the people supporting these measures are adopting them not because they care about safety at all, but have another agenda.
