Is this a Spinal Tap tribute? I assume you mean 1-2'?
I was once drafted on my folder, late at night, on cs3, in the rain, at about 12mph. The guy was so close I couldn't see him over my shoulder or in my mirror. It was very dangerous as people step out all the time so emergency stops are common and with heavy rain, we couldn't communicate. He was a stranger, and I assumed he was waiting to pass me. It was only later I realised he must have been drafting.
I tried to learn drafting for the first time on Sunday. She slowed, I pedalled fast to catch up, got into her draft and stopped pedalling then had to brake, she started pulling, and (accidentally) dropped me. Repeat. It's a skill to learn.
