So this goes back to the loss of the DIN in vehicles. Vehicle manufacturers shot themselves in the tire decades ago when they stopped caring about DIN space and started forcing themselves to develop and then abandon the lead position on vehicle infotainment. Carplay isn't very special when you consider any 90s and early 2000s vehicle with a DIN slot or two can have all the exact same functionality as Carplay with unlimited upgrades for around $200 in hardware. The OEMs failed to innovate and outright hubris meant they would not roll-back to what worked well for everyone. Apple deserves to eat their lunch.
