I was reading the thread about 4x4 technology and it got me thinking. How necessary is the new technology that goes into trucks and cars these days? You have cars that park themselves, let you know when you're falling asleep or drifting lanes, and supposedly will stop before you slam into the car in front of you (although I've seen the Volvo demo where the car slams into the truck...ouch). Is technology making us better drivers, or taking over the job for us? I usually enjoy driving, and love a good road trip. Do I really trust the person driving next to me that can't parallel park their car, or is too busy reading their email to realize that they're about to get into an accident?
