To me this reads like "Cars have won, give up on walking and biking in your cities."
That's just not a solution. Just because car lobbyists have successfully ruined nearly all US cities and a good amount of European ones doesn't mean we just sit down and continue to let it happen. I agree public transport is a huge part of the way forward, and I even agree that walking/biking in harsh weather isn't exactly ideal, but we can't let the most simple human ways of existing in cities (walking and biking) go to the wayside just because car companies want us to believe they're bad or unsafe transportation methods. Want to walk in the snow? Put on some boots and wear some layers with a scarf and a hat. Want to walk in the heat? Wear a hat, sunscreen, and a light shirt and pair of shorts. It's not _that_ hard.
