I have been a not-quite-rabid proponent of cycling since I could pedal myself to school then work. I don't believe the infrastructure can handle even 20% more EV demand right now and certainly not what is being proposed by governments and individual corporations. Yes, the demand for EVs will cause the infrastructure to be improved but by the time demand is pushing government to improve infrastructure, it's far too late. I live in a city where most houses can't run a hair dryer and a microwave at the same time. There is no way this city (the 6th largest in the US) can handle it now, nor within 10 years. We have regular large-scale outages due to overloading (summer AC use) and physical accident related incidents (downed tree branches or the garden-variety impaired driver/car chased by the police who runs into a pole with a transformer on it. ) An electric bus can do it here but in all reality, people in this town need to bike more or they need E bikes or scooters, or whatever smaller version of personal transport they choose. Most people who live here have a commute less than 6 miles, that's a reasonably quick bike ride for a healthy individual or an even faster ride on an E bike.
I'm not saying cars are bad, I have two and I love them both. The diesel Mercedes is the Mad Max car that I'll be running on filtered fry oil after diesel becomes too expensive. Both the Benz (currently non-op) and the Fiesta make more sense in this city than any of the big trucks I see on the roadways, with huge tires just wasting miles of chunky tread life on the city streets. That's proof that people have more money than brains.
Yes, we should save the planet, but personally unburdening oneself of their individual carbon footprint by shuffling their direct aromatic hydrocarbon use off to a powerplant somewhere out in the burbs isn't the solution. Improving public transport and incentivizing it in big cities would be a huge step. Incentivizing riding a bicycle or even a scooter would be big. Getting the EV cart ahead of the infrastructure horse, is like buying an electric toy for a kid and forgetting to get batteries by Christmas morning. A lot of pouting, tantrums, and angry stomping will result, and very few will be able to get around.
