| > So make cars pollute less Physically impossible to have them pollute less than methods of mass transportation. Mathematically, even. Just divide the number of people carried per pollution caused by cars vs trains, bikes, or even buses. There's nothing you can do to make cars competitive. > Figure out how to filter microplastics from our food and water "Just figure it out", ok. But even then, an ounce of prevention is worth the pound of a cure. > Figure out what's causing asthma in children A little random but ok. I'm guessing grinding up rubber and metal particles into the air right next to where said children live isn't the best for their lungs. > Not sure how obesity is related. Maybe improve the food supply? 1. Wake up 2. Walk 30 feet to your car 3. Sit as you drive to work 4. Spend 8 hours at your desk 5. Walk 30 feet to your car 6. Sleep 7. Why am I fat?! Maybe improve the food supply?! > A lot of these are solved with electric cars which are increasingly more competitive. Virtually none are, an electric car is still a car, see point 1. > Why force people to regress towards a worse product rather than address these technical issues? Highly dependent on your definition of worse; I'd argue the sort of streets and environments you can find in the Netherlands [1][2][3] are way better than in the US. Not everything is a technical issue that can simply be solved by better engineering.
