Is this a scam ?

Battery warranty 8 years, cost less than engine overhaul in a similar spec ICE car. Generally they slowly degrade. There are people in the States have done 400,000 miles with less than 10% loss of range. Face it, electric cars are here, now and viable; they need to get into the lower end of the market now but the Chinese and Indian manufacturers will see to that before long.
The problem isn't running out of charge. but actually running out of electric supply.

Yes Dave W did u or did u not part with hard earned cash to Rockstar Plant, don’t be ashamed to admit the hundreads of thousands you parted with???

How often did you have to stop to charge up & how long for each time?
Can't remember now, used a website "A Better Routeplanner" but charging stops are determined basically by bladder range rather than battery. By the time we have all been to the loo and had a coffee, the car was ready and waiting for us.

S ignoring the fact that all cars have running costs apart from fuel, where were you charging, not Ecotricity at 60+ p per unit I assume?
nice trip though?
Most sites now charge 30 to 35 p, which is sensible considering the capital involved in charger installation. We were using the brilliant Tesla supercharger network, for "free" (paid for in the price of the car), but for those having to pay with the Model 3, I think it is now 25p per unit.

Most charging will be done at home and off-peak. Octopus Agile tariff actually goes negative at times - during the recent strong winds they were paying people 2.3 p/kWh to take off peak electricity. The problem with supply is at peak times, and with smart metering and smart charging, 90+% of charging will be off peak. As more solar is introduced, daytime off peak is likely.

The ability to generate enough electric and supply enough electric for the 30million cars on the road today, is going to be a sticking point. To get the amps to the domestic charge point would mean a serious overhaul of the existing grid capacity. I'm just curious!!!

I agree. If everyone plugs their cars in to charge when they get home from work at what is already peak demand on the grid, the system isn't going to work. With smarter chargers connected to the internet with external control to match charging to grid supply/demand it is doable. For an instant charge at the end of a working day you're going to need a way of storing a lot of electricity at home or have the buffering capacity in the grid.

The trouble is so many opt as my daughter did, for her new all electric golf, just charging from a 3 pin plug. It needs to be on all night if she is to get anywhere near a battery full.

I'm really sceptical about the electric car 'revolution'. I just don't get how the electricity will be generated, even if its 'green' without a massive increase in turbines,solar,hydro etc which all require massive amounts of materials at a cost to the planet. That's before the grid is upgraded and all the new electric cars are built using god know what rare earth elements in their batteries etc. The recycling of all this stuff is going to be massively problematic too IMO. I think its a con by the automotive industry. I think the government should invest in public transport not just HS2 instead.

If it is a massive con by the automotive industry, why are they resisting so much? They need to be dragged into the 21st century.

There are huge issues to be sorted before we all drive electric cars.
currently it is fine for the few on the roads, stopping off at services for a high speed recharge each Tesla charging point delivers 150 Kw to 1 or 2 cars split.
this means each point would have a power draw of 375 amps on the local 3 phase network 240 volt per phase supply!
if the service station has ten points it is going to require 135 amp supply if hooked straight into the 11,000 local network.
go to your average M1 service station and check how many people are topping up fuel which will give on average double the range of the largest electric cars.
I think coffee sales will go through the roof, if they still have power to boil the kettle!
There are no reasons at all why these things cannot be sorted in the next few years, but knowing our government, I very much doubt it.

IMO the Tesla Model 3 will sell well & service station charging capacity will be stretched, especially once the other manufacturers jump on the bandwagon if company car tax encourages it. Battery storage would be a sensible way of storing energy for a quick dump into a road vehicle.
