When you think of it, if one hasn't a 'friendly' electricity kwh rate, and say have just got the standard default tariff (i.e like MILLIONS of the public has), it isn't really worth them buying a transportation pod.
For eg, a default British Gas standard tariff is, I think, now 54p per Kwh. So say this person has a Trophy with the 64Kwh pack. Then it costs 64 X 0.54 = £34.56 to charge from zero to 100%, for say a real world 250 mile range?
Now, my Mrs' 1.5 MINI Cooper gives a great 52 mpg regularly (by my own calculations, not the on board computer). So 52mpg = 11.43 miles per litre, so that's 22L per 250 miles (the probable real world range of a 100% charged, Trophy MG4). At say £1.62 per litre, 250 miles costs her about 22 X £1.62 = £35.64..... Almost exactly the same cost!! And of course it takes her about 60 seconds to fill (charge) her MINI for that range, as opposed to 7 or so hours.
So why would someone not only buy the 4, but also go to the expense and hassle of paying a solid £1000 on top of the car costs for a home charger, with the work done by the installation people, for negligible running cost gains, if they are like millions of people and on a standard default rate electric plan?
Granted you get free tax (for now), but faced with those calculations, why would someone opt for a transportation pod?
