Think I've said this before but the major issues are:
Not having a dedicated driveway or garage at which to charge the car is a pretty fundamental problem. Many Scottish houses do not, and even the new ones are often built with separate shared parking. The problem there would be that an illegal parker in your space means no use of the car tomorrow.
Not everyone is a commuter. Some people only use their cars for longer distance journeys. Even with a 200 mile range, as soon as you go beyond 100 miles you risk being stranded if there are no charge points. Or if they are all in use.
The cost of a hotel room for an overnight charging stop totally outweighs any fuel cost saving. (and when you consider the extra energy used in an overnight stop, overall energy use is probably more than returning home with an IC engine)
The majority of the car market is for used cars. Buying new is very expensive in terms of depreciation. Used electric cars will be a big gamble due to battery condition questions.
We are constantly being told to turn off lights to save the limited amount of energy provided by renewables. One electric car motor, 2000 lightbulbs or more. No calculator needed for this one. It is simply unsustainable to add transport to the demands placed on renewables.
In the Netherlands the have the same issue with parking.
What's being developed here is just shared charge areas. So multiple cars can charge.
Therefore you don't need your private parking spot.
Not everyone is a commuter, but like said before, the numbers show that more than 90% is a commuter.
I guess the car market really depends where you're from than, because here most cars are new or just 2nd hand cars that are less than 2 years old.
Your last comparison is totally absurd (sorry for saying it that blunt). You need to compare it how much energy and emissions combustion engines produce.
According to new regulation most countries are not gonna pass them if they don't change anything about it at all.
Besides, the amount of fuel (oil) is limited and will be gone at some point, so do we have a choice?
It's not a matter IF electric cars will become mainstream. Most governments WILL make sure the become mainstream because they don't have a choice.
And I think for the long distance an hybrid electric-hydrogen car would be pretty awesome.
