Yes it sounds like a Daily Mail headline although it should probably be the other way around if it was a DM article but there is a hidden or should I say silent issue here.
Personally I am very happy with the reduction of polluting cars and motorbikes with the popularity of electric vehicles but I really think they should be fitted, as standard, with some sort of noise to alert people, cyclists and other road users they are there. Too many times now I have been scared the hell out of when a electric bike or car comes whizzing passed without a warning. It is bad enough when you can hear a car or bike revving in the distance getting closer but at least you know it is about to happen and can adjust you position/style.
Anyway just a thought I think is worth talking about before someone gets injured. Not a fan of noise pollution either really but I am sure there could be a balance.
