A lot of fast chargers are over $1 per kwh so unless you have access to home charging there isn't much room for savings.
For sure, EVs are far more efficient at converting a kwh of energy into forward motion, but if we assume 35 mpg (9.25 miles/litre) for the gas car, we need about 970wh to travel 1 mile. A modern EV can manage a mile on ~260wh, almost a quarter of the gas requirement.
There are public charging networks in the UK averaging 92p/kwh - we know we need much less energy to move the more efficient EV, but even with this adjustment fuel cost per mile looks like:
petrol at UK average today: 17p/mi
Electric at very expensive public charger: ~24p/mi !!
At many chargers, there are no savings at all. For comparisons sake, that 92p kwh would be just 28.6p on the most expensive domestic electricity supply, and charging at home would be ~8p per mile on the worst possible tariffs.
I've probably done some bad math somewhere here, but I think the broad picture is correct.
Which is 21p per mile, for my petrol car
at 98p a kwhr its 20p per mile.
but in practice the electric car is 3 pence a mile for me (average car charging price for me is 15p a kwhr)
Of course, thats why I've been clear all my assumptions are for 260wh/mi, which I think is a very fair middle ground figure to compare to a 35mpg car - one can pick far more fuel efficient gas cars for this comparison too, the possibilities are endless.
I think your numbers still illustrate the same point though; if you can't charge at home, an EV is not necessarily cheaper to fuel, and the gap between the public charger price and the cost to a private consumer with home charging is still far too big. 98p vs 15p is staggering.

Wales – 75% of households have – or could have – off-street parking and EV charging England – 68% Scotland – 63%
In London, sure, most homes don't have off-street parking and ev charging, but then only half the households in London have a car

Even in Wales, 25% can't. This isn't a figure you can ignore.
And that's a hypothetical, it relies on landlords playing ball etc. then there's the social issues. On the north of England we have lots of terraces built for mill workers, these aren't owned by the richest on society. So then you're in the situation of charging the poorest more for transport. And these are necessarily on towns with good transport links (think 1 bus and hour).
Now clearly that 25% and 20% won't overlap exactly, but they will overlap a lot
When 80% of cars in the UK are electric and 20% are those households who rely on public streets to store their belongings for 23 hours a day, then sure that will be a problem
Given that there's only about 2 million electric cars in the UK, yet 18 million homes which can charge electric cars, that's a long way off.

Almost everyone I know with an EV charging at home just reused the 240v dryer socket to avoid paying for a dedicated fast charger. It's often cheaper too to have an electrician fit a new 240v socket instead of the dedicated charger as well.
Let me guess, you live in Germany? :)
Three phase power is definitely not 100% in the EU. Not even in Germany, though adoption does tend to be higher than neighboring countries.
And FWIW, I find that my induction cooktop works wonderfully on plain old 240V 40A, so I do not think it is a requirement to get three-phase for that ;-).
It's used for dryer, stove etc.
[0] Okay, technically 240V did not become official until around 1967, but the split-phase design was there from the beginning. They capped it at 240V to stop the creeping up that had been going on in the earlier part of the century. This is why you still have a lot of people (not all of them old enough to have been alive in 1967, oddly enough) that refer to 240V as 220.
Unless you are regularly doing upwards of 150 km/ day, it's fine.
