False. Petrol is kinetic energy stored chemmically while with electric cars you first have to convert that kinetic energy into electricity and then back into kinetic. An additional conversion brings more inneficciencies, and that is before counting in the 50% weight gains because batteries are heavy as fuck. This brings more load on the tyres, they need to be replaced more often, as well as the roads themselves.

Electric cars have been around before ICU cars and its always just one battery breakthrough away. If electric cars were so great, they would not need subsidies.

The data from fishcakes’s video doesn’t support your claims. Not sure about tires, but I doubt those are any major sources of emissions…

They are mostly made out of carbohydrates… what happens with all of the tyre? A small fraction is recycled because it is energy intensive. How many tyres are changed per year?

Just think from base principles. EVs are a lot hevier because energy density per kg of battery is less than that of wood. Heavier vehicles = more energy used to change speed and direction.

And raising the average weight of a vehicle by one third does what to depreciation of roads? Ever seen what a poorly maintained bus lane looks like?

So many things in a complex system that it is impossible to say if it is better or worse. What I do know is that they are more expensive than ICE vehicles even with massive subsidies.

They are fun toys and have interesting applications in car sharing in cities which is not possible with petrol cars.
