And do have also the ability to produce electricity with a usage pattern that permit self-charging the car? Electricity grid are a bit complex to be kept up, to be more precise generators need time to step up produced power and time to step down, that's why we make large enough grid to average the load on generators counting on a big enough user base to have a nearly constant load on the grid, small variations of loads can be sustained. Slowly charging a car, test on few friends cars, means around 15-20A witch yes is not exceptional BUT if many people charge their car during the night that means a spike load, a significant one, on the grid, something no actual grid can sustain. Remember: we do not have "big hyper-condenser batteries" to absorb a spike while generator step up and we do not have "energy sponge" to dump excess of energy once a load drop and the generator need a bit to lower it's produced power. That's the very same problem of domestic p.v.: if they are connected to the grid it's the grid that sustain initial spike while the solar inverter step up, and it's the grid sustain final spike receiving the excess of energy while the inverter step down. If your load surpass injection limits your inverter will disconnect loosing power completely to do it's best to keep a constant frequency on the grid.

We have invented the CONCEPT, since so far exist only on paper and small scale experiments, of smart-grids, to mitigate that big problem: in a smart grid nodes talks each others to say "hey, get ready to produce more energy, I'm about to soft-start from x to y", generators can potentially answer back "don't, we are overloaded" or "ok, we get ready for you". E.v. in the game can provide batteries + inverters to quickly intervene backing up the grid segment per segment. Similarly in case of disruption they can keep a house powered connected to it's micro-grid + anti-islandic system to avoid injecting to the grid. So far we haven't such networks, we have only ideas and experiments. It will take decades (one it's not enough, for all not so small countries) to implement them at a certain scale.

> If you live in a city [...] then you should be using mass transport.

Witch is an enormous issue alone: mass transport are very costly and very inefficient, they are efficient only when fully loaded, exactly when people do not like them for the crowd. But we need to move 24/7/365 not just in peak time, so public transports are complicated and bad in terms of energy saving and outcome service. They are pushed just because there is a hyper-push against personal ownership and autonomy at any cost. But the truth is that public transports are needed in dense cities, but are absolutely unsustainable and dense cities are. Some want them, just because dense cities means mass surveillance where very few can rule many easily, also making them dependent for anything. Even accepting that big liability in cities you still need cars: you have sometimes to go outside, you have to transport heavy/bulky stuff, witch can't be done on public transport. People who work in the city need vehicles just because a plumber, an electrician etc always need a not so small set of tools with him/her etc.

> However the cost of both an electric car and the solar installation isn't worth it

True, and that's why to push the Green New Deal they artificially hyper push up energy prices, both to finance massive private investments in energy production and transmission and to force people who can to buy the Green New Deal stuff and the others to starve sliding toward State subsides at State (of course, not Democratic state but one run by private neoliberal interests) rules. That's already happen. When I've made my new home I know it was not economically interesting BUT I've smell rodent and decide to accept the capex, now in just few years it start to be economically interested. E.v. are still too expensive for their MTBF but I'm pretty sure in few years with energy prices that keep skyrocketing they'll became interesting. As a result I'll spend far more than without the neoliberal economy but still far less then embracing it. Most who live in classic homes and cities will simply have no choices: they'll sell their own homes to some private giant that will rebuild them in new homes for who can afford to buy or rent, or to the State in exchange of provided social housing at provided condition reaching the (in)famous "In 2030 you'll own nothing" from the World Economic Forum agenda. If you are in the UK I suggest Mark Carney (ex head of UK national bank) book "Value(s): Building a Better World for All" it's essentially written black on white, of course, with different tones, but equal picture for the future.
