Rain sensing windshield wipers. Seriously, are you really that stupid and/or lazy that you can't figure out when you need to turn on the wipers or to flip a little switch or turn a knob? The first thing I thought when I saw those was 'great, just one more thing that can break'.

A close runner up would have to be the heated windshield washer fluid tank. I've often driven in -30 F or colder weather and not once had the windshield washer fluid freeze up on me, not that you really need it in those temperatures. The only possible application I could see would be clearing a frosted over windshield as often happens when first starting up. Is an ice scraper really that hard to use?

iPod connection... I saw an entire car commercial based on that. Who buys a car for that?

I remember when the new remodled VW bug came out it had a little built in vase to put flowers in on the dashboard. I don't know if they still put this in those cars, but either way I think it's pretty weird and useless!

That steering wheel thingy.

Why don't they just put laser/optical sensors on the front to keep the car between those painted colored lines on each side of the lane, a motion sensor to keep distance from the car in front and to avoid pedestrians, and then interface it to GPS to change roads at the right places?

I keep on having flashbacks from the 80s about a car that when you grabbed the handle to open it it would trigger the feul injection. I was a kid and remember thinking that was weird.

A few years ago there was an ad that proclaimed the car to be "the first with a mp3-CD player included standard". For those who need to buy a specific car rather that go to a place like Car Toys.
