Adaptive Cruise Control is wonderful - I recently did a long-distance drive across Europe (~1000KM), and I swear I went through 100KM of roadworks. Adaptive Cruise Control would have been amazing for that (plus the other traffic jams caused by accidents/etc).

I have seen a good implementation of blind spot monitoring, in a VW, where it was just a simple light on the appropriate side mirror. Unobtrusive, but obvious enough that you're unlikely to miss it.

The most recent car I drove (a Ford Mondeo, I think? It was a rental) had a number of those but I never really noticed them. The only time it beeped at me was when it thought I wasn't braking hard enough to avoid ramming the car in front (oh, and the proximity alert).

The reverse camera and related sensors were really useful because (a) I don't drive an awful lot, renting a car maybe once a year, and (b) because I only rent cars, I don't know them well enough to know if I'm gonna get through a gap or turn a tight corner, so having something that beeps at me to say I'm close to a wall is handy.

If I was driving the same car every day, some of these features would probably be a lot less relevant.
