I read some analysis that we should be promoting plug-in hybrids rather than electric vehicles. That would spread limited batteries over more cars. A range of 50 mi would be enough for most commutes. Long drives would be covered by fossil fuels. The result would more people using electric than current electric cars or your proposal of local electric and ICE vehicle. The question is if it is worth pushing now. It might make sense to have incentives cover plug-in hybrids and push car companies to switch existing models.
