I had some (very occasional) drafting partners on a 20-mile commute some years ago. I didn't know them, but the way they rode (and the fact that they took their turn) suggested that they were up to it. When I was tired, it just made my day if I saw one of them looming to front or rear. It was part of the middle 10 miles and really broke the back of a hilly and difficult run.
I draft my kids and they draft me. I have no problem with it
per se, but it is a risk. One time my daughter's QR skewer tore the guts out of my tyre and tube. Not her fault; I'd just whipped past her to take the front and then had to stop in a hurry. Tyre and tube were ripped betond repair... Grrrr...
Another risk of drafting: There was a risible OP on this forum some weeks ago. The author had swerved to avoid a crashing rider on a club run. As he was so close he had nowhere to go and damaged his bike. He opened the thread to see how he could sue the council for crashing into a kerb, ignoring the fact that he'd crashed because he was riding closer than his ability suggested he ought to.
That is the danger of drafting.
But I encourage it and it always improves a ride. If it's for more than a mile or two, do take your turn....
If it's in town between red lights and roundabouts, that's not really drafting. It's just a traffic line.
