Ya I also agree. Battery from these cars will be a problem if not properly recycled in every country. Currently battery storage technology is primitive in terms of lifetime. I think no battery will last for more than 5 years max. So if all the toxic materials go to soil there is no point. If we reduce travel everyday by carefully designed system for country or city, we could reduce pollution. Of cause it may bring loss to car manufacturers and governments car tax where more than 200% in some countries . I think economy does not worry about environment until it is too late.
