Tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food.

    I learned recently that speed limits are determined by studying the speeds driven and setting them at the 85th percentile.

    So what we can do to lower speed limits is to find a place they’re doing a traffic study and repeatedly drive over them at very low speeds.

      We can lower the speeds driven by putting bushes right next to the lanes. They increase perceived speed.
