Why is Tesla one of the few car manufacturers who actually pushes real updates to their car's dashboard system (and for free, others charge absurd fees if they do give minor updates). I hope that by 2020 it is the expectation that your car will continue to update and improve its interface over the years you own it. I say this because people point to smartphones as always being more updated- and there's no reason for this.
