Electric scooters are all the rage  many cities  the world. The electric-powered two-wheelers are helping people nimbly zip  traffic and effortlessly get  town. However, they have also brought problems and safety concerns. Many scooter riders disregard road regulations, ignore traffic lights and illegally ride  sidewalks. A major scooter manufacturer has started selling a speaker that will alert pedestrians and other road users  the scooter's presence. Segway is marketing a new speaker accessory that can add V12 engine noises to its scooters. Alternatively, the user can plug  their music device and the speaker will boom  the rider's favourite tunes.
Segway's $150 Ninebot Engine Speaker can play music or revved  sports car sounds  23 hours when fully charged. The speaker syncs  the scooter's accelerator, so the faster the vehicle goes, the louder the speaker's rev sounds are. Segway said its engine speaker acts as a continuous warning to anyone  earshot that the rider is approaching. Many road safety analysts believe the speaker could reduce the number  collisions  scooter riders and pedestrians. However, critics are concerned  an increase  noise pollution. They say the beauty  electric engines is their silence. They believe a simple beeping sound is sufficient to alert other road users and a V12 sound is overkill.
