Well, I didn't personally, but my editor (who owns two MC's) did. He filed his report here:

Great to see the MC forging into this territory, even if normal folks can't yet get one. Here's some meat from the article, for those that don't want to click-through:

But in the electric Cooper, changing your accelerator position does not vary the torque of the engine, it simply changes how fast the engine wants to run. So when you hit cruising speed, if you back off the throttle in the normal way, the car slows down immediately. As in Right Now! There’s no “cruising throttle” position, so you just have to learn to hold the throttle for the speed you want.

In addition to the accelerator, braking the Cooper E feels different. As you transition from the accelerator to the brake, the car’s already slowing down more than a gas-engined car just by virtue of withdrawing the accelerator input. But when you step on the brake, you’re not initiating any friction from the brakes at first. In the interests of science, we should really have tried some experiments, but we didn’t want to attempt any panic stops in the middle of Pico Blvd. on a Thursday afternoon.

 

Thanks for posting the article. That is one big a$$ battery on page 2.
