okay, I know that doesn't scan 
I haven't driven for years and years, so I've never had any fancy features on a car.
one car I'm looking at is Hyundai i10 or i20 and there are these "driver assist" type features that will alert you if you're drifting into another lane etc. Also some cars have this screen cam where you can see details of where you are parking etc - Is it worth it? I suppose I always drove without them so probably not, I don't know. Be interesting to hear views.
I do want to get front and rear dashcams. Are they a nuisance in any way or very easy to set up? My computer is quite old so I would need to be sure the software would support them anyway.
Satnav - I thought the kind that actively warns me about traffic jams etc might be useful. Does anyone have any recommendations? I don't know how well they update etc.
I also can't decide about air con. I do remember a couple of horrible days being stuck in a very hot car in a motorway jam but I suppose back then I just put up with it?
Final question - is it normal for cars to come with alarms built in because I actually would prefer mine wasn't. I live in a London borough and will often be parked where I can't see the car or hear the alarm so I don't want all the surrounding poor souls to suffer listening to it.
interested to hear everyone's experiences. Re cameras and sat nav, I wouldn't look to spend a lot.
Thanks wise MNers!
