Due to the semiconductor shortage in 2021 everyone realized that cars these days integrate a lot of electronics. The average number of computer chips per car has increased a lot in the last decade. It is clear that the new applications require high-speed interconnects that are not possible with the initial, low-speed interface types. But[...]
