Few things mess up a driver's mojo like someone going 26 mph in the interstate fast lane. But, surprisingly, the slow drivers themselves may actually be engaged in a kind of sport:

The Ford Mustang Mach-E electric car can hit 60 miles an hour from a standstill in 3.5 seconds. Fergal McGrath prefers to keep the needle stuck at a grandfatherly 40 mph. He's after a different kind of bragging rights.

Mr. McGrath is a hypermiler, someone who tries to coax as much mileage as possible from their fuel, whether gas or electric. The practice requires driving at a plodding pace to conserve energy, around 40 to 50 mph on a gas-powered vehicle. The efficiency sweet spot on an electric car can be agonizingly slow—sometimes below 30 mph.

I mean, look, that's...sort of cool, I guess? It's not exactly an Olympic sport or anything, but it's a neat, weird sort of competition.

Still. You can understand the sheer unpleasantness of being stuck behind such a driver. We've all been there. We know what it's like to just not be getting anywhere on the road.

Meanwhile, the dedication that people have to hypermiling can go beyond intense and run into the genuinely absurd:

In 2018, Sean Mitchell and a companion spent 32 hours in a Tesla Model 3 circling a 1-mile loop of public roadways dotted with chain restaurants and hotels near Denver's airport. Puttering along at 25 mph, a highlight included receiving burritos from friends via a fishing net hung out the Tesla's window, to avoid stopping, Mr. Mitchell said.

Okay, all of that is very bizarre. But...and you know we're all thinking it...

What did they do for bathroom breaks during those 32 hours???
