What's the problem with electric cars?

[sixaparrat]

One problem, that's overlooked by most, is the weight of a BEV.
A Telsa Model 3 performance is 1850 kg or so, it's ICE equivalent, say BMW 3 series is 1500 kg or so, an increase of 340 kg. Across the board this will result in much increased damage to the sub-formation and substrates of roads, resulting in more roadworks, and more expensive (and more environmentally damaged future roads, because the damage caused is exponential to the increased weight.
I. e. In the dim distant past when I studied highway Engineering, lifetime of roads was designed for 25 years based upon the damage caused by Passenger Car Units (PCU).
Generally 100,000 PCU per day would wear out a road in 25 years.
However a 15 tonne lorry (the largest generally on the road at that time) caused the same damage as 300 PCU, nowadays a 38 tonner is worth 33,000 PCU.!

We had a XC40 twin motor recharge on weekend test drive, it's 30kg heavier than my XC90....

Quite. I can only assume that the BBC's Environment and Climate correspondents are away on holiday this week, whilst the Science and Technology reporters proudly "hail" the first Virgin Galactic tourist flight.

Otherwise, I'm sure the focus would have instead been on six people having pi*sed up the wall the equivalent CO2 load of ~135k miles of 45mpg ICE motoring in the space (ged it?) of just 1.5 hours.

Mining for gas & oil tends to make pretty big messes too, Exxon Valdez anyone?

Weight issue isn’t just BEV Cars though. This got me all rilled up when the chap starting blaming BEV cars for potential issues in multi storey car parks. Since 1960 cars in general have been increasing in weight. Compare an original escort to todays focus/Mondeo. SUVs are the biggest issue, with everyone driving around in overweight cars including all ICE SUVs, such as range rovers weighing over 2T.

Lithium mining is quite complex and the largest mines for the mineral is in Australia (strict regulations) and also South America in salt flats and is quite a complex process to extract. All high level company’s, especially on the stock exchange have strict codes of conducts and procedures to prevent slavery and child labour. Bribery still occurs, however slavery child labour is a highly penalised offence and all sub supplier chains are thoroughly audited. (This is part of what I do as a job). The photos Forge shared are unlikely to be linked to anything and only used for propaganda.

I realise that cars have Ben getting heavier over the years, but the increase due to battery weight is a much bigger step, and if we all changed to BEV overnight, we'd need 4x4 to cope with the resultant potholes.

Everyone moving to SUVs already had that extra weight. A standard electric car (hatch, saloon etc) weighs about the same as a Large ICE SUV, but no one cared about the weight issue there…. Yes large electric SUVs weigh a lot but that’s where the issue is, everyone wanting larger cars. You can’t have a large lightweight car.
