Apparently I've bought a fly-by-wire car

If I understand what I've read right, then the front wheels turn based on steering wheel and speed. More at lower speeds. Sounds like a good idea and in this application it's not something you really notice, so I guess it's just a tiny difference.
It's also got "panic brake assistance" which means it senses how fast the brake pedal is pressed down. If you press it really fast it gives full brake effort before you can press it all the way down.
This might not be new to you, but this is the first car I've ever owned and I kept up more on car technology many years ago, so it's new to me.
