I'm a strong adherent of electric transportation, having recently upgraded from an electric moped to an electric motorbike. I've also used these rental scooters all over my city (Vienna, Austria) to get around and I find them very convenient when, in a pinch, the excellent public transportation doesn't work out. That said, I think there is a major modification required to these devices that will radically decrease the accidents: they need to make a sound. Seriously, riding an electric vehicle is one of the most pleasant, enjoyable experiences around - but getting hit by one is easily one of the worst surprises imaginable. Every week, I count the number of people I could've hit full-force with my electric motorbike, if I hadn't been paying EXTRA attention to the street - on average I have one to three near-misses every week. I don't blame the pedestrian - after all, I'm keeping EXTRA attention for them, since I know my weakness: I am silent as heck in a city full of pedestrians whose survival skills have been honed on hearing whats around the corner. Those days are over. We need speedo-synthesizers now. I've half-considered writing one myself (synthesizers are my thing) but I'm pretty sure its something that needs to be so reliable that it has to be built into the OS. I wish Apple would address this. It'd be so much safer on the roads if we had great sound design alerting pedestrians to the hooning idiot coming around the corner. And thats the issue with these electric scooters - too often they are being operated by idiots. And yes, I class anyone riding a scooter without at least a bike helmet on, to be a full idiot. tl;dr - Scooter companies need to start hiring sound-designers to keep ignorant pedestrians on the pavement before they get demolished by the silent, excellent transportation options hitting the scene ..
