Ford "MyKey" keeps teen drivers under 80 mph

The new, chip-embedded car keys will also keep young drivers from cranking the car stereo, as well as sound alarms until seat belts get fastened. Looks like the carefree days of "American Graffiti" are over, in more ways than one.

The Associated Press reports that an "unspecified number" of 2010 model Ford cars and trucks (including the 2010 Ford Focus, due next year) will come with the MyKey feature, which will eventually get rolled out to all Ford, Lincoln, and Mercury models.

Besides the option of keeping young drivers from going over 80 miles per hour (leaving a slight buffer over most state speeding limits "in case an unusual situation arises," the AP notes), parents can also set MyKey to sound in-car alerts if their kids accelerate past 45, 55, or 65 miles per hour.

Among other possible MyKey restrictions: A volume limit for the car radio (to "44 percent of totally volume"), along with chimes that sound once a minute (and mute the radio) until drivers and passengers buckle their seat belts.

Naturally, teens aren't amused by the coming MyKey feature; indeed, a Ford survey found that 67 percent of teen drivers "don't like" the idea (no kidding). Then again, when asked to factor in the possibility that MyKey might give them more chances behind the wheel, the "hate it" figure drops to 36 percent, according to Ford's survey.

OK, but are built-in speed limits for cars really a good idea? You could argue that all drivers need to be able to accelerate away from danger—especially if you're trying to pass a line of cars while facing oncoming traffic.

That said, I can't remember the last time I truly needed to speed beyond 80 mph, for any reason. And then there's this sobering statistic (PDF): More than 6,500 fatal car crashes last year involved drivers aged 15-20, while speeding was a factor in 31 percent of all fatal crashes in 2007.
 
So, parents and teens … what do you think? Are set-in-stone speeding limits a good idea? What about the car radio and seat-belt restrictions? And for the teens: Would you accept a MyKey if it meant getting more chances to drive?
