>Gas cars got fast out of nowhere because it moves units and CAD changed everything for engine design.

Gas cars got fast because sufficiently high quality computer control matured to the point where making a high power for its size/weight engine that both met emissions standards and reliability expectations and did so at a reasonable price point was doable.

The ability to actually build the hardware has preceded the ability to run it in a reliable and emissions compatible manner ever since we've had emissions rules. Having better FEA software so some engineer could shave a gram off a piston, get his bonus for achieving his KPI and ensure half a million engines start knocking at 120k on the dot was never the bottleneck.
