This Peugeot 308 was trying to kill me with its "lane assist" in a construction zone, forcefully steering the car towards the concrete barrier because the painted lines on the road were tapering towards the concrete barrier (due to the construction). I finally found out how to turn that off _after_ nearly being killed.
Make my car less like a desktop computer, please.
My favorite is _waiting for the car to boot up_ so I can turn on the air conditioning in the sweltering heat :)
There's also the joy of fumbling through terribly-designed touch screen menus so you can turn off the radio that for some reason auto-tuned to some nearby station. Since my FM transmitter wasn't broadcasting audio I guess the car just decides it needs to get something pumping through the speakers ASAP.
The other hilarious thing is the cruise control pretty much slamming on the brakes because someone merged into my lane 300m+ ahead (not even slightly at risk of driving into them because they are about the same speed as me). I guess the system that detects an obstruction ahead cannot tell that it's moving at the same speed as me. Not surprising, but regardless, can I please be the driver of the vehicle?
Oh yeah and how about those software-driven dash gauges that feel like they have a full second of latency? The ability to customize the UI skin is something I want for WinAmp, not my car's tachometer and speedometer.
