A year ago I would have agreed with you. In between then and now I had a job (not IT) delivering and collecting things in a rural area. I kept on driving a few hundred metres, ringing a doorbell, doing the real job and repeating. Even out there I didn't feel comfortable leaving the keys in the ignition. So now I can see a point for keyless ignition - but for delivery drivers, not for most car drivers (including me).

For most people and most situations I still agree with you. Keyless ignition and similar innovations create additional complexity and additional points of failure for limited real benefit. I can't help thinking that a lot of this "stuff" is going to cause problems in the 2nd hand car market in the future. Cars with functioning engines, safe brakes and suspension and acceptable (in the sense that it keeps the weather out and the people inside and doesn't have sharp bits to hurt people) bodywork will be rendered unusable/saleable because the windows don't open or close and the doors don't lock or unlock, and that's before you get to all the pollution control bits.;-)
