This is exactly why insurance rates are set out the way that they are.
If/when I have kids that will need cars, I will get them an older and heavier safe car - ideally the old boxy Volvos or Saabs.
Those you can drive full speed into a brick wall and then roll over 3 times and still get out of it with cuts and maybe some broken bones.
A Vette, regardless of how fast it can go, is designed to be light and fast, not safe - esp anything older than '95 or so - not that I feel the new ones are all that safe either.
There is no way I'd put my kid in a Vette or a Civic - I would want something better in a crash at any speed since kids are retarded.
