Obviously you can't do such a simplistic direct comparison between horse emissions and car emissions. How does leaded petrol play into this comparison, particulates, etc.
- cco 4y agoYou're totally right, my comment was far too simplistic. However it captures the feelings at the time, cars at that time were far "cleaner" in that they smelled a lot better, did not clog streets with excrement etc Obviously play the car out a few decades and the emissions were _not_ so clean.
