>What a stupid argument. Lets all buy 2nd hand cars because clearly then we'll never need new ones.
good idea. why not ?
>The point is that the new cars being introduced as old ones wear out should be as clean as possible, not that >everyone should ditch their car for a new e-car. It's a long game, there is no infrastructure for everyone to switch >anyway.
does your house wear out ? Do you sell it and get a new one every 5-10 years even ?
no - of course not - you 'maintain' it - and by doing so it last indefinately. Sure, in the end after maybe 100 years there's some 'ship of theseus' going on, but have economically replaced old parts as required, recycling them as necessary.
Do we still need new houses ? sure - growing population, and a small amount of poor housing being renewed - but would you ever even consider knocking a house down after a certain number of years just because it's old ? of course not - it would be mental. And yet we do exactly that with cars.
A modern car is much the same as a new and has arguably no defined maximum lifetime anymore than your house does.
My X5 has done 150K miles and drives like it's just came out the showroom. In other 50k it might need a reconditioned gearbox, perhaps in another 150K miles, a new engine. The bodywork shows no signs of rust whatsoever after 11 year, so I imagine that will be just as good in 10 years time.
The people buying new cars are not the people who have previously run a new car for the last 20 years until it was no longer maintainable - if they were you might have a point. They are people, that 'buy new cars'. They are the main contributors to any environmental pollution. It doesn't matter whether they are buying an EV, a diesel or a ferrari - they are still the no.1 polluters.
The economics of new cars, now only works with a worldwide market because of the longevity of the cars these days. How many 10 year old cars do you see on British roads ? Not a fraction as many as there should be - because they have been shipped out to eastern europe, china, etc.
As long as the supply of new cars continues unabated, the supply of 10 year old cars to china is unabated, and the inefficient recycling of perfectly good 20 year old cars will continue (since who in China will want a 20 year old car, when 10 year old one are coming in all the time).
