For Maximum EV Efficiency, Stick to 25 Miles an Hour, Ignore Angry Drivers
When I was in college, a research program at my university found when vehicles traveled at multiple variable speeds, this led to an increase in crashes.
Intuitively, when a hypermiler slows to 25 mph on a 60-mph highway, other drivers will move into other lanes to pass – or on 2-lane highways, swerve into the opposing lane to pass. Lane changing and passing leads to more crashes, injuries and fatalities.
But if you do it in an EV, you are all good! Because virtue!
For most people, driving across country at 25 mph will not be feasible.
