If the only metric for how long products should be used is how long they’re commonly used, we won’t be able to make longer-lasting products.
Electric cars with standard tires trade a reduction in carbon dioxide emissions for an increase in fine particulate matter. We need a solution.
Let me ask this provocative question:
Why is it legal to drive a 30 year old diesel but when your 3year old, much cleaner car doesn’t pass the smog check, you’re not allowed to drive it?
Unfortunately, it’s true that a heavier car (like an SUV) is often safer, simply because it’s heavier.
