Price! No batteries exist yet to do what you want and I don't know, 100 other issues that will not be addressed like charging. Not like driving along an interstate (which I never do.. I take the local roads to every place. Cant see the country on an interstate)I’d have no issues at all buying an electric sled once they get the range up to being the same as a gas sled. As long as the weight is similar what’s not to like?
