The recent advert where Arnie is trying to convince people to buy ICE cars (as a prank) puts this in perspective. He rocks up in a Hummer that is making normal car noises, the noises that car drivers like: https://www.youtube.com/watch?v=rXodSqMpuUQ https://www.youtube.com/watch?v=rXodSqMpuUQ ..but in this advert the noises sound so naff and quite... noisy! My vehicle of choice is a bicycle and it is very quiet. But I have a bell. I can give a gentle ting to let people know I am behind them. It would be a little odd to me to have a bell that continually rattled just to inform anyone who I can't see that I am behind them. How many guide dogs have I maimed and slaughtered? Zero. And this is sharing the same paths that people go on specifically to walk their dogs. What next, someone walking sixty yards out in front with a red flag? What happens if you live near a road that has slow moving traffic during rush hour? This could be nice and silent as it shuffles along. But it will be making these nanny noises from all the tin boxes. Apart from anything else I thought it was a solved problem of having cars stop if something is in the way? Automatic collision avoidance? Can't we have that and a softer 'bell' instead of the aggressive 'horn'?
