So, to overcome range anxiety in an EV, all I need is a friend to follow in an ICE then when the battery is dead, get a tow until recharged before just carrying on as per usual?  😲

That would of course be one way of achieving that.  A more likely scenario would be for to to call out the breakdown organisation of your choice and persuade them to tow you a few miles to a charger rather than flat-bedding you there.

Good thinking, realising you want the ev in front due to zero emissions,  you wouldn't want the ev behind and subject the poor ev driver to be inhaling all those nasty ice gasses.

I feel like we are finally getting somewhere 🤪

Not quite the same thing but when I had a PHEV (Golf GTE) it could be set to charge as you were driving.  Doing it this way charged it quicker than plugging it in (using a proper EV charger).  I always wondered why it was able to do this.  BTW at the time I had my petrol paid for but not my elecricity so doing this was slightly better for my pocket if not for the environment.

The new BMW phev has the same mode to charge itself, and takes the mpg from around 50mpg to around 35mpg to charge the battery.
As witnessed by 2 of my colleagues who test drove it over a couple of days.
It's an option in my work place for those not quite ready to take on a battery only car.

A gateway EV if you will.... 
No fast charging, but pragmatically if it gives the level of comfort with charging a battery needed to allay range anxiety, then maybe gateway vehicles are what's needed.

A strange quirk of the Zoe ZE40 is that while the max charge rate on a charger is 22kw, it will actually regen at up to 43kw when going down a suitably steep hill and/or breaking sharply. 😀
My guess would be it's a limitation at the charge port while the internal charging mechanism  is capable of higher charge rates ??

However most people don't use all of the range much of the time.

We still have a diesel Skoda for anything that can't be done with an EV, but after a year with the Ioniq, it's likely this will be changed for either a PHEV or BEV, especially as it's almost 6 years old now and the mileage is getting rather high on it.

The Ioniq is hopefully doing 2 trips to Birmingham next week (125 miles each way, all of it 70mph roads), so will a) need to be charged when there to as close to 100% as possible and b) will be the 'final' step off the range anxiety for me, as this is, apart from twice a year, the furthest I need to drive in one go.

The 2nd car is likely to have a much higher range than the Ioniq if a pure EV, so that's the above problem solved too.

So I travelled the 400 miles to deepest darkest Englandshire today from brightest sunniest Scotlandshire. 🤪

What can I tell you about the Tesla, its a lying b'stsrd. There's no way you are getting 360 miles on UK roads unless you are driving about the fens at 50mph.

Electek report the 2021 long range 3 as having an 82kwh battery, well at 265 miles I'd used 65kwh and 91% of that when I pulled up to a supercharger.  When I plotted that charger it said I'd arrive at 2% (The next one was 40 miles, it was just too much of a risk to try) but I guess 15 miles of 50mph roadworks!!! Extended my range a bit (returned 204wh in the most boring road in the world).

That was 100 miles exactly at 65mph coming through Scotland (actually the most watt intensive part of the journey at 312wh took 15% of the battery,  just the first 30 miles going through the hills under central Scotland) and then 100 miles exactly at 70mph, and then an attempt to do 75mph, but the roads were too congested and several road works. (I'll try again on the way back up)

So if the car had 75kwh available it would do 300 miles, as the average for the whole journey, including a few ton plus chases was 250wh, but it doesn't have that available. 
I'd guess at just shy of 72kwh is available. 
So I'd say at a push I'd get to 280... maybe even 290.

And yeah im sure there is more there after the zero, but the car wasn't happy about the 7% I'd driven it to and avoiding potential damage, but meh, its there to be used as far as I'm concerned. 

A wee pic of the 144kw charge rate, which unfortunately had dropped to 50kw when I came back from visiting the services, likely due to the other 3 teslas that had plugged in to other stalls in that time.

Perhaps saying its a lying B is an overstatement,  in reality it handled 70, 75 and even 80 far better than 65 in Scottish hills, so the energy used to climb hills is what kills the range... im not sure that's a huge surprise, as the car is pretty aerodynamic. 

The adaptive cruise control is great, and made for a much calmer journey than normal.

It strikes me that it's actually a perfect car for stop start traffic as the cruise control brings it to a stop, and creeps when other cars move.

I thought I'd just add onto this post from a week ago.
So the first thing to say is that lower England on a Friday afternoon absolutely sucks. 
Took nearly 5 hours to get from Reading to just above Manchester. 
Attempted several times to do 100 miles of 75mph, but it was just a no go in that traffic. 

Arrived at charnock Richard services with 19% left after 215 miles of stop start, clear road, roadworks, stop start... rinse repeat. 
Plugged in at charnock Richard and walked into the services to .... well you know.
Went upstairs to get food, but serious lack of tables and it looked like a cattle market, so decided against.
Grabbed some snacks and headed back to the car, spoke to a mate on the phone for a couple of minutes and realised in the 31 minutes I'd been parked I'd gotten up to 79%.
According to the tesla that would get me home with 4%, mate said "done be daft, wait ten minutes more" and I thought, nah let's see what happens.

So believe it or not I arrived home with exactly 4% pretty good guesswork on the tesla part with over 185 miles.

I did the whole journey with cruise control set to 75mph and an indicated 260wh.
What was interesting was there were warnings on screen about the range "stay below 75mph to reach destination " flashed up any time I went to overtake, clearly doing 76mph... ish.

So my conclusion with incomplete data (always a risk) is that the tesla is just as happy at 75mph as it is at 65mph, which is why you see so many of them in the outside lane. In comparison the leaf suffers quite a bit from 65-75mph, my own test was a 40% drop in range at 75mph, probably why you see so many leafs in the inside lane.
