Wait, what? The price differential is not that significant, there are also cheap new EVs, and driving a 30 year old car with EU fuel prices and mandatory technical maintenance costs won't be a much more affordable option, and there are pollution laws like Paris which ensure that older, more polluting cars can't enter city centers. If new cars become more expensive, it's likely to cause some limited decline in usage, but saying "nobody won't be able to afford new cars" is useless hyperbole.
