Seen an increase in this recently. Must be the summer and tour influence.
When out riding I seem to attract wheel suckers. Some are polite and at least make their presence known although I've yet to have somebody offer a wheel*.
I-ve been drafted when training for time trials, had a guy sprint past me, blow up then draft me and today a guy draft me despite a tail wind and me doing 15mph.
Is it ruder to turn round and tell them to fxck off, launch an attack or simply explain that its like tailgaiting and a bit dangerous if you don't make your presence known.
* I realise that the number of people drafting is directly correlated to my awesomeness
