Heated seats: on days it would be cold enough to use those I get into the car wearing warm clothes with enough insulation not to feel how cold the seats are. Some people leave home in shirt, drive to the office and walk 20m from the car park, not me.
Electric stuff: which will fail sooner or later.
Climate control: a heater and windows.
Audio gubbins: if I drove more I’d fit something simple and aftermarket with a USB socket and hi-fi quality speakers. On the integrated things there is just too much to go wrong.
Sat nav: I like maps and knowing where I’m going. For long trips I print out the Via-Michelin route.
Hands free. I’m a believer in stopping when convenient and phoning back when stationary.
I like comfortable seats, they can use as much naff plastic as they like for the rest, except: the steering wheel, I’d have happily paid more for leather rim.
It’ not so much Luddite as liking simplicity, a bit like riding a bike with hub gears and puncture resistant heavy tyres on a Winter commute.
