If you were my kid, there is nothing you could do that would make this better.
A, you're stupid, forgetting I had this device installed.
B, you're not trustworthy in the first place, which is why I had this device installed.
C, my lack of trust in you has now been confirmed as appropriate.
D, your speed showed a failure to respect the law, the rights of other drivers to be safe, and your own safety.
Guess who's not getting their license until they're an adult and I can't stop them? (Or, if you have a license, guess whose license is being scissored in half?) Guess who's never going to be able to get my keys again because I'll keep them where they're not accessible, even though it's inconvenient? Guess whose friends' parents I'll be phoning, making sure they know my child is irresponsible behind the wheel and absolutely should not be allowed to drive their child anywhere?
Sorry, your irresponsibility has a cost. You literally could have killed someone, and that's never an acceptable risk.
