A couple questions...

1. are their projections for a reduction in the absolute number of cars and/or a reduction in the size of cars as AVs become available?

2. could something like transfer learning be part of progress on climate and other common problems? For example, perhaps Brazil or the US also want to be able to produce cheap solar panels. Do we need to go through the same learning curve for solar panels as China did? More broadly, how specific is a learning curve? Is China applng lessons from solar panel production and HSRs to manufacturing in general? If so, is this further motivation for the US to make sure we master at least some areas of manufacturing?
