&gt; He is sub 20 years. I&#x27;m thinking more like 40-50 mark.<p>Perspective:<p>* 60 years ago, we didn&#x27;t have highways.<p>* 45 years ago, seat belts weren&#x27;t required.<p>* 40 years ago, we expected engines to last 10s of thousands of miles. We didn&#x27;t really understand crumple zones. Open containers and even drinking while driving.<p>* 30 years, we added fuel injection, computers, and airbags.<p>* 20 years ago, the hybrid car, better fuel efficiency, and side airbags<p>Imagine what we&#x27;ll know tomorrow.
