I agree we should reduce pollution wherever possible, and modern diesel and petrol engines are much cleaner than they were in the past. There is polution in making all cars including EVs, it's just that it is mostly not in the UK. However climate change - what climate change? For every scientist you can quote asserting that climate change is real, I can produce one with the contrary view. There really needs to be a grown up debate about whether it is real, what its impact is etc. Eliminating CO2 is not required - we need it to grow crops - see Harry Metcalfe's video on this; he is a motor correspondent and a farmer.
(around 15.50 minutes in for a diagram). Further, what we do in the UK to reduce CO2 is absolutely minuscule compared to the additional CO2 being produced in China and India.
Having said that, I would buy an EV if the package was right. By that I mean price, recharge times and range predominantly, but however the technology is still evolving. If I buy an EV now, the technology will be out of date within a year or two - battery technology is still improving which will give the sort of range required to work in all weathers, without range anxiety and bank holiday queues at chargers. I don't want to be a guinea pig - I'd rather buy the finished product.
Probably because of all the electronic gizmos on them - from eletronic parking brakes (what's wrong with a handbrake), computer screens to operate everything from heating to audio, do we all need heated steering wheels, lane assist etc? Some are EU requirements, some aren't.
