Cars' climate control and radio technology is generally pretty intuitive: Turn the dial to the right to get more heat/air conditioning /sound/bass, and turn the dial to the left to get less.
Then in-car telematics systems came and mucked all that up. Figuring out how to change the temperature with some of these systems can induce stress headaches, because the geniuses who designed them thought it was a smart idea to make something that used to take one step now take five.
Some telematics features are awesome: Read-aloud text messages, voice control, syncing a phone's music with the radio, automatic 911 calls, and car status reports can make driving safer, more cost-effective and more enjoyable.
But can't we figure out a way to make that all easy to use? -DG
