Most of the Tech on the I5 is magical power seats, didnt think I would use them, but I do, a lot, for moving around. Power tailgate is brill, approach the car an you get warning beeps, an then it opens. You can do it from the fob as well. The Self Driving Aids work seamlessly and accurately. The car essentially drives itself on the motorway. The blindspot monitoring helps a lot. Lane keeping assist is mild and works. There are 2 sections of road it gives a kick, but I know where they are and am expecting it.
The 360 camera is ace. I have to check around the car to see where garage cat is lurking when pulling away from the drive. Best thing us the Head Up Display, (HUD) it should be standard in every car.
