If I had someone riding my tail close enough to matter, I think they'd suddenly find that I can be very erratic in my speed.
It's not that I'd care that they're there; anyone trying to draft me must be really slow. The problem is, I've never been involved with drafting, and it'd be dangerous for someone to be that close to me.

I think anyone who tries to draft someone that they do not know is being dangerous. There's no way they could tell what that person would do.
