On the one hand, I was trying to drive an unfamiliar bike through a subway tunnel at breakneck speeds, and the sooner someone who knew what she was doing could take over, the better.

On the other hand, for her to take over, I’d have to drive it by myself for—

“How long is this sync going to take?” I asked, watching the tunnel lamps whip by my head in a blur.

“About two minutes…give or take!” Nicky said. “The sooner I start, the sooner I’m done!”

I tried to find my balance on the bike, and hoped that my iPhone’s mic wasn’t sensitive enough to pick up my whimpering. It probably was. “Okay, do it.”

The multi-function display dashboard flickered, and a tunnel map appeared with a green line tracing the way through it. “Just follow that route and you’ll be okay. Handing off control…now.”

We wobbled, but only a little bit. At this speed, keeping my balance while going straight was easy. I just hoped this route wasn’t going to involve any tight turns.

Or for that matter, any turns at all.
