single track road, I'm climbing from Bow Brickhill upto the church. Geezer comes down the hill in a Laguna (silver, look out for it, I'm pretty sure he's a local), anyhoo he basically sits in the middle of the road & drives at 30mph which is pretty intimidating if you are cycling. I have options: throw myself on the dirt or stick to the tarmac & maintain my position.
So I thinks to myself, I'll keep my position & tip his wing mirror with my finger tips, it'll make a noise & he'll try harder to give way avoid the 2 guys behind me. Unfortunately guy is closer than I thought & the whole flat of my hand slap his wing mirror & slap it back against his car. He stops & 3 point turns nearly takes out my buddy in his hurry to get turned & comes back to have a verbal at me in the church car park.
I explained (gently and reasonably) that he was too close, too fast & nearly had me off & his excuse was that the hill is steep.
Then my buddy got to the top & vented loudly & with not a little anglo-saxon vernacular included, that the guy should drive a little more considerately.
Anyhow, STWcollective: When you are climbing how much room would you like to be given by a car doing 30mph downhill toward you? And how would you advise a car driver that (in your opinion) they are too close?
