Interesting about the lack of noise...
...because just yesterday I nearly hit two pedestrians coming down a hill on my electric bicycle as they just stepped out into the road.
The road was recently converted to a one way, that is, UP the hill. So nobody bothers looking the other direction any more as they cross over.
Obvious conclusion, fit a V8 noise maker to my bike, oh and to every other normal pedal powered bicycles in my town too as the locals are far too stupid to bother looking.
And before anybody goes querying why I'm going the wrong way down a one way street, well its either that or the pavement, or a hundred odd metre detour which goes along a busy and dangerous main road with a huge bus lane where a bicycle lane should be. It was (or maybe just felt) less safe for me when it was a two way road!
There is a cycle lane on it too, but its on the right hand side when coming down the hill, and so drivers always think you're passing them on the wrong side.
Its all very complicated ;-)
