If you start fully charged at the top you've got nowhere to store the regen work. It is actually a problem, modern EVs are designed on the assumption you can regen brake and hence the conventional brakes are smaller to save weight and cost. If you've got this hypothetical person who starts every morning at the top of a big hill with a fully charged battery you run the risk of them setting their brakes on fire.

So Noggin would need to work out how much charge is added during the descent and make sure she always leaves that space available when charging at the top, doable in theory if that can be calculated and set.
The calculations would need to be done with the slowest possible speeds to factor in aerodynamic losses. Make it a dry road as well.
Ermm - for accuracy, forget dry roads (well, for at least 4 months of the year!) and go for snow or wet!!

My only worry with that plan is what the price of petrol and excise licence will end up being
There will be billions lost in fuel duty so they'll almost certainly drive up the tax on petrol and road tax on petrol vehicles. Q? Where are they going to get the rest of the ££s from?
Can't really just up the price of electricity as they can't separate what's domestic and what's not. My bet is road pricing. Quick trip up the motorway? Kerching! Probably end up paying twice for a petrol car then.
In the news that Shell are 'offering' to install 50,000 roadside chargers by 2025.
Charging for free, forever*
* I made that bit up. They see money in it, so will HMRC.
Gubbiment will get their money somehow. 'Red' electric, anyone?
I can't see how taxing the roadside supply impacts all those that charge up at home* and they'll want a pound of flesh from them. Can they distinguish what's used for cooking/heating....without forcing you to put in a second meter? I suppose they could charge more for electricity overnight but that's when there's loads of excess.
*They'll probably be tricky to automatically charge for road use too.
Doubt is not a pleasant condition.
But certainty is an absurd one.
Voltaire
They could tax more on any electricity over a certain quantity. I.e. assume a 'reasonble' figure for household consumption and then say anything over that is charging. Or lighting a grow room.
Double whammy effect 'cause it encourages you to use less overall.
Or you only tax electricity that's going into a higher power wall charger and use a smart meter in said charger.
Or you could increase road tax to a point where it covers the revenue lost from fuel duty - it'll be unfair on low mileage users, but why would the government care about that.

Our 'smart meter' logs gas and electric use. It wouldn't be too difficult to fit a similar system.
But it's a good question, I'll ask around (unless Dazzle knows?).

I'd want to know a lot more detail about the trip. How long did it take? What the weather was like? How many drivers? And more.
The link says:
July, and "Ford employed the services of drivers with petrol and diesel economy records already on their CV"
Elsewhere:
"The electric performance SUV was driven by BBC transport correspondent Paul Clifton and Fergal McGrath and Kevin Brooker,"

An average of 32mph. It smells fishy but possible given Tesla do much better at speed than European EVs.
Google says, right now, 14hrs 21 mins, or thereabouts.
So what concerns you about a much slower time?
The price of an overnight hotel for starters. Squeezing the most range isn't that important, I wonder how quickly they could do it including charging time.

You want a hotel to not smell fishy? What?
Anyway, you need Dazzle to answer questions about the balance between speed and refueling.
Given than it only took 45 mins to charge it up again I'd have thought you could do it quicker, with more stops. I don't think that was the point of the exercise though.
Porsche have done some similar stuff with the Taycan, but with more focus on going fast and charging.
This isn't exactly electric car related but its climate control and covers a bit about "Clean Hydrogen" production.
Oh and the vid contains some swear words.

So, I can potentially retire in just over 4 years. I bought my 5 series last year brand new, only the 2nd new car ever.
I'd really like to go electric next time, but tbh, I just can't see me being able to afford one. For anything with half decent range and power, you're currently looking at easily £45k plus. The new Kia ev6 is going to be £50k for the more powerful version, for a Kia?
The last thing I want to be doing is spending a large chuck of my monthly income on an electric car. I may well just end up keeping my 5 series for many years after the supposed 2030 cut off date. Not that I actually think that will happen, I think it'll get delayed by 5 or 10 years.
My only worry with that plan is what the price of petrol and excise licence will end up being, making my car uneconomical (it's a 540i). At this stage, I don't know what I'm going to do?
Probably a large compromise, lose a load of power, luxury and range.
Once you retire why will you actually need a car at all? I don't plan on having 2 cars in the house by then. Maybe an ebike but deffo a motorbike and then 1 car we both use.
