Why would anybody buy a sports styled motorbike and ride it like a commuter bike? Almost every ride out I've been on involves slightly spirited riding (ie fairly quick pace) with a fuel stop so typically around 150-220 miles in range. I use my motorbike for commuting but also much much more than just that (touring, rallying, track days - ride there/use on track/ride back home, visiting different venues which could be quite some distance away, occassionally doing some shopping etc). For some of these an electric bike could be utilised but certainly not for all of them.
The truth is that electric vehicles have some extreme limitations. If you want to limit yourself to only being able to use the vehicle for certain circumstances then by all means go ahead and buy an electric bike/ car. Do not however try to ignore the very significant limitations that these vehicles have.
I rode to germany last weekend and back to see a show. That was 880 miles in 4 days with luggage and all ridden at moderate pace (ie around the speed limit on motorways etc). I could not ever have dreamed of doing such a journey on an electric vehicle. I used to work away from home for a while which involved stopping over in a B&B monday to friday (about 160 miles from where I lived). I could never have contemplated that with an electric vehicle. I sometimes go away to rallies or shows and most of them don't have provisions for recharging. None of the parking facilities at any UK company I've ever worked at had recharging points and trailing an extension lead from one of the buildings wouldn't have been tolerated from a health and Safety view point (tripping hazard and also cable length would have been excessive leading to possibility of overheating the extension lead or reducing the current so much that recharging times are multiplied.
Vehicles do have collisions from time to time which would involve potential damage to batteries. Both Lithium Ion and Nickel Metal Hydride batteries have health concerns (carcinegens and fetal harm to name some of the most prominent). I have heard of cases whereby electric vehicles were left to burn because full body respirators weren't available for the fire fighters.
Production of the batteries is an extrememly Carbon Monoxide rich producing process. The processing of the raw elements for the batteries produces significant amounts of pollutants equivalent to running a conventional petrol powered vehicle for a couple of years.
Industry likes to extol the virtues of new technology as it can make money out of them but after a while the flaws in that technology become evident. For example CD's do not last for ever etc.
You may have an opinion about about electric vehicles but everybody else is also allowed to have their own. I can not see electric vehicles being a realistic transportation source unless exchangeable common fit batteries are developed which can be exchaged at realistic costs.
As others have mentioned where does the power to recharge these vehicles come from? Wind farms are one of the least efficient forms of extracting energy and only ever work if there's wind (god help this country if we get a sustained cold/ dark period without wind as parts of the country will end up being cut off - or we'll simply end up buying electricity from overseas at whatever mark up they want).
