I've given up waving following a rather nasty experience a month or two ago:
I was riding along a quietish country lane (yes, with my lad), enjoying the unseasonably dry weather and clear skies, if not the unseasonably high temperatures. The route chosen had worked out well, we were both in a good mood, legs were feeling great, and our lunch stop had been nutritious, delicious and warm. A few birds were practicing their spring songs and the air was smelling great before the field fertilising really started. We were having a good time out together.
I noticed in the not too far distance as we rounded a slight bend in the road another cyclist heading towards us on what looked like a reasonably serious bike, if not a full-on carbon racing machine. He was keep a steady pace, not bimbling but clearly not on a self-imposed time trial, clearly enjoying the feeling of freedom as he sped along the country line as well as the sights and smells, much like us, although probably slightly slower.
Now, because I am a friendly and polite person, and want to set a good example to my son, I prepared to acknowledge his presence. I am on my road bike, so a generous wave, as per a Pashley rider, would have been inappropriate. I wasn't in full training mode, so a subtle lift of the finger would be equally inappropriate. Instead I mentally prepared for a four-finger lift (almost, but not completely removing a hand from the handlebars), a slight tilt upwards of the head, and a barely audible "hi", which would be the most appropriate, I judged.
He approached further. There is a perfect time to start the wave. Too far away and there is an awkward pause from then until the moment you actually pass when neither of you knows what to do. Too close, and it looks like a "passive agresssive" "Why didn't you wave first?" acknowledgement.
We entered the zone of perfect timing. Muscle memory kicked in, fingers and head moved without being individually directed by my mind, and the vocal cords tightened and did their thing. And then I saw it.
He was riding an e-bike. An electric assisted bike. One with a motor.
There are some things that you cannot take back once delivered, and the tilt and wave were two of them.
I NEVER want to find myself in that situation again, so until the government mandates a different coloured helmet, or use of a warning drone above the head of all cyclists using electricity to help them, I shall not acknowledge another rider, at the risk of making the same almost fatal mistake again.
Hope you, and anyone I might meet on the roads will appreciate my fears and not judge me too harshly because of it.
