First off I am kind of surprised at the damage to the semi...80 mph or 100. Especially since a corvette, is so low to the ground.
Anyway...either way, this is a tragedy, where I truely don't think the parents can be to blame. Although, considering most parents, they most likely are blaming themselves.
Secondly, whether the car is a corvette, or Nissan, or even a cycle...driving ability comes with practice and maturity. And kids going down the street at 30 mph in a station wagon can be just as scary. They are more easily distracted...especially now... Have you ever seen a new driver talking on a cell phone, changing the radio station and checking out their lip gloss in the rearview...SCARY!!
Truly I think if you want a kid to drive with a little more responsiblity, having them get a job and make payments for the car, probably isn't such a bad idea. They appreciate it more because they are paying for it.. It is not a privelidge to be taken for granted.
