Rates would be lower if we all drove at the same speed, no matter what that speed is. Setting the speed limit at 55/65 doesn't make everyone drive at 55/65.

- kej 10y agoThat may be true, but doesn't change the fact that we've done this experiment nationally, and adjusted for other factors that are known to affect speed, there were fewer fatalities when the limit was lower. Setting the limit at 80 doesn't make everyone drive 80, either.
- eridius 10y agoThat's why you set it to the 85th percentile speed, as the article explains, rather than picking some arbitrary speed and expecting everyone to go at that speed.
