Keyless entry can flatten battery as it is always 'on' looking for the right chip to appear by the car, push button start is a gimmick - I have it on Civic and is far less intuitive than turning the key an extra 8th of a turn, the only upside (especially with Honda engines, where you can't hear them running) is that once engine is started if you push the button again it does nothing ( I did try it out of interest). Although I have had Civic for 16 months now, it took me a while to get out of habit of trying to turn key to start it - if I was in a hurry i would probably revert to trying to turn the key
As for leather seats you can keep the horrible slippery sweaty things, much prefer textile - as for heated seats - we don't live in Norway and they are just a needless drain on battery - only thing I would like is cruise control (just plain vanilla version would do - no need to sense vehicle in front and slow down etc.)
Blind spot detection - Even though Civic mirrors are large, I still have long ingrained habit of looking over RH shoulder before moving to RH lane on a motorway, and triple checking when moving over to LH lane, as some people still think they can overtake on the inside
just hope Honda not going the same way as French and spending money on gadgets at the expense of the engineering of the rest of the car - just look at the reliability of gadget laden french cars, and how many fail their first MOT
