The work done on real-time Linux has benefitted the open-source OS for years, but it was only this week that Linus Torvalds admitted its last piece into the mainline kernel. Exactly what took so long?
If i understood the article correctly, real time means predicable and reliable, not necessarily fast. It’s common in medical devices, avionics, etc. So this is going to benefit embedded devices the most.
First I heard of this, but since it seems to be just some software that runs on the hardware of car manufacturers it seems rather unlikely. But very theoretically possible, if the car manufacturer was using default process scheduling in a CPU constrained machine and now switches to real-time scheduling in an update. But that was possible for years before this news, the code has just been mainlined to the default kernel now. If the car manufacturer cared about that they would probably have done it already with a patched kernel.
Does this mean android auto won’t be slow in the future?

If your speedometer/tachometer is a screen instead of dials, it’s extremely likely it’s running Linux, too
So still somewhat useful in the auto space
If it’s more than a few years old, it’s extremely unlikely it ever sees this kernel update.
