The building that I live in is going to run out of physical space for electric meters long before it has issues with electrical capacity. My neighbor opted to forgo having a charger for his Model 3 and instead put one into the garage of his weekend home (he doesn't drive much during the week so he'll be ok).
Given existing equipment on the market now, our building can support maybe 10-15% electric cars. If you are designing a new building, there is no limitation. Our condo board has been searching for a solution and has found some things that are "promising", but nothing that will solve our problem before we run out of space. Again, this is a physical space limitation for the meters, not electrical capacity. And it's a problem where the solution will have to interface with the existing built environment and the existing electrical grid and the existing safety codes, etc. If all you pay attention to are single family homes with garages, you'll never know this is an issue until sales take a nosedive in big cities.
In a new building, you just design the electrical system so this is a non-issue. In an existing building, it's not so simple. Any state that has a lot of condos is going to have 100+ years of condominium laws that govern the ownership and usage of space in a condominium. You can't force someone to share their space and you can't authorize someone to enter someone else's space.
In Germany, 1 kWh costs over 30 cents. As far as I know, that's one of the highest rates in "Western" countries.
If electric cars make sense in Germany, then they can succeed pretty much anywhere.
Edit: https://en.wikipedia.org/wiki/Electricity_pricing#Global_com... lists Germany price/kWh at 0.35 USD, making it indeed the most expensive Western country at least by quick eyeballing.
We drive 10K miles per year across two drivers. My daily electric (LEAF) costs me $0.05/mi for energy (and I love it). My wife’s SUV costs $0.10/mi for gas and a few pennies for oil (and she loves it). She pays $600/year max for fuel. That covers about a month of Tesla car payment.
There are many reasons to like a Tesla. It’s almost surely not the cheapest way to motor though. A $5K Honda and investing the difference will be wildly cheaper during the ownership period (including no need to carry collision/comprehensive insurance!) and have a much higher residual value (in the investment account). To me, that should be more compelling to many people.
A lot of people should do the math on the model 3. The math is current car payment + 90% gas payment = new car payment on a model 3. The remaining 10% is what you pay for electricity.
