I think that they should remain banned - they are a danger to pedestrians and motorists. Most children these days have absolutely no road safety awareness and an are more than likely to zip across a road in front of a car (no doubt the car driver would be blamed for it too). In my area (a quiet residential area) during the winter, there are idiots sledging down the hill during snowy periods with no regard for any traffic on the main adjoining road, also they damaged my neighbour's car last year by losing control and scratching the rear bumper and wing - why should these segway things be any better or safer?
