Are there any financial incentives for this? Even if a technical solution exists, are there incentives for EV manufacturers to support it?

This is one of the big things I'm looking for before committing to buying an EV as my next vehicle. Even if Tesla "opens" their charging network, that's not the same as having a single, universal charging standard which anyone can build out themselves. A "USB for cars" would be the ideal solution.
