I don't know of any technical reason why #2 is hard. Its just a matter of getting the power company to do it and setting up incentives so that EV owners will us

  My electric company had me install a separate meter for my EV charger to manage time of use. Benefit is that only my EV costs more in the day, downside was the cost and time to have it done.

  It's hard because those who design EV, PV etc do not own them, do not understand them. They simply execute some order "do so", ignorantly. That's why only few weeks ago we have seen an initial standard for biderectional DC support. That's why there is still NO PV inverter who actually output 400V DC for stationary batteries who happen to be the same in EVs avoiding wasting 25-30% of energy in useless multiple transformation. That's the issue of private led initiatives: public research propose visionary solution, implement them, give them to the public with some standard concepts. The private sector then pick and implement. Like we do now, anyone try to offload research costs to customers, push their own standards and nothing really work.
