electronics in cars are still relatively new. As companies gain experience, things should get better. One thing that will help is a willingness to pay more to keep cars on the road, which we're probably going to need to do anyway, if the current trends in EV are pushed further.

The short term carbon footprint of manufacturing a NEW EV is just as bad or worse than the carbon footprint created when manufacturing a NEW ICE vehicle.
The both need wheels, tires, seats, wires, upholstery, powerplants, fuel storage, glass, paint, etc. all built in a plant that burns fossil fuel to power the robots and keep the lights on.
The main difference between the 2 versions (EV vs ICE) is the footprint created during the lifetime of the batteries.
When the batteries die and need to be replaced, there is a huge 'uptick' in the cf of the EV, that the ICE vehicle will not share.
Not to mention the cf of the discarded EV batteries, which the majority of the ICE vehicles will not contribute to - due to having different battery types with better recycling options.
Making brand new EV's will not save the planet... there are already too many ICE vehicles on the road for the EV market to have a significant impact.
On the other hand, if a manufacturer were to design a factory kit to convert an EXISTING ICE vehicle to electric (or other alternative fuel), THEN there could be enough of a change to influence the market... refurbishing old cars with new technology to require less energy.
Adding MORE cars to the streets - regardless of their fuel source - is NOT the answer to the equation.
