Cost, range, and number of electric cars are rather artificial metrics—I think measuring the cost, range, and number of cars in total would be much more in the spirit of the post, which haven’t seen any surprising departures from trends. As for batteries, a ~15% decrease in cost per doubling in cumulative number of lithium-ion batteries produced combined with roughly exponential growth in the market has meant a smooth trend over the past few years: see this source.
I believe it’s also easily checked that there’s no significant discontinuity in cost to orbit. Starship could be promising, and Musk’s goal is an extremely ambitious $2M/1000t to LEO, but even that is only 30 years or so on the current trend line.
On the contrary, the graph of launch costs you link seems to depict Falcon 9 as a 15-ish-year discontinuity in cost to orbit; I think you are misled by the projection, which is based on hypothetical future systems rather than on extrapolating from actual existing systems.

This seems right, thanks.
