Of course, you and I are pretty much on the same page. The complexity and cost would be staggering to redesign the whole thing. But maybe there are smarter, incremental ways to go about it. Perhaps mandate a special paint for lane markers to include magnetic paint or some kind of nanotech. We already do repairs on roads, repaint, replace &quot;cat&#x27;s eyes markers&quot; etc, so modifying the materials used should be easier.<p>I fully agree it&#x27;s going to take a long while for everyone to adopt this, and one of the keys will be proving the AI tech - which then becomes a chicken and egg problem. Maybe Google&#x2F;Tesla are laying the groundwork for that, and on second thought maybe I&#x27;m wrong about us thinking about this the backwards. Perhaps this &quot;over-engineered&quot; solution (for the lack of a beter word) is exactly what we need to then later optimize for &quot;the right way&quot;.
