You may be right about the copyrights in the individual unit, but I was talking about the underlying car OS in response to the commenter who said “most car systems run android”. QNX is a real-time operating system which is required for something like a car. Another for instance would be Microsoft Auto which Ford used before switching to QNX.
In general a modern car will have dozens or hundreds of computers running their own software and communicating in a sort of API fashion usually through something like CAN bus. Most of these systems can’t afford to wait on something to boot when you start your car.
In very general terms we are talking about the main difference between an Arduino and a Raspberry Pi.
The other commenter is on the right track but the chip controls both USB and PS/2 as well as others;
In the 90s and 2000s, for x86 machines, slower I/O was handled by a chip called the Southbridge which worked in conjunction with a chip called the Northbridge that handled faster I/O like IDE and PCI. Later these were integrated into a single chip and, as of recent processor generations, into the processor itself.
AFAIK ghosting and key rollover are issues when using PS/2 but it can offer some milliseconds off latency when used in high cpu games.
