1. Solve climate change by buying 1-2 tons of newly mined and processed aluminium, rubber, plastic and lubricants! There are 32,000,000 cars in the UK alone. That's welp over 32,000,000 tons of carbon-heavy material to manufacture to replace current stock (in the UK alone). If we focussed investment on better catalytic conversion, standard fuel technologies we'd be able to totally minimise damage.
2. New electric car costs 26tons of carbon to build. Average carbon output for mid 2010s Audi on 4000 miles per year is well below one ton and possibly as low as 0.5 tons. That's before we improve emissions technologies - they aren't fully developed yet.
3. A new electric car is a piece of technology. What we know about all technology in the last decade is that it has in-built obsolescence. The car manufacturing industry is evil but we still have cars on the road which are over 50 years old. Electric cars will have in-built obselesence to force consumers to continually switch to new models. Old models will be no good for the second hand market. Evidence? Look at your phone and everyday appliances. They aren't built to last. Electric cars will not be built to last.
It's fine if you want to disagree with me on this one, but I think electric cars will be one of the biggest environmental disasters of all time.
