In the UK it already means all the electric car drivers program their cars to charge when it gets really windy (or did). Once grids implement a sane variable pricing system and manage transmission capacity properly electricity prices are unlikely to go zero or negative. EVs alone will probably soak up excess demand (& contribute back when pumped storage starts running dry).
