I drive on an experimental highway surface daily. It's quieter, but uses an unorthodox drainage system (that at least feels less controlled in wet conditions).

I drive on an experimental highway surface daily. It's quieter, but uses an unorthodox drainage system (that at least feels less controlled in wet conditions). Only real use statistics will say for sure if it's safety-equivalent to standard surfaces. The state DOT is testing this on me and tens of thousands of other people daily at high speed. Sure, I suspect that they did smaller scale testing before deploying it, but so has Tesla. So tell me: what's the difference?
