As has been said, RTFA for those with questions about the speed limiter. Yes it really only limits to 80mph, but that's better than nothing, even though it doesn't do anything for city streets (duh). The seatbelt/volume control is a good idea (most new cars have the seatbelt cry-alarm already). Only time will tell how "hackable" the system becomes. Ford can easily route the system's power through the display and mph/rpm gages and/or lights, thus getting around the fuse-trick. Slap a disclaimer label on the "blackbox" should anyone tamper with it and then complain. Any other way to get around it entirely would require ripping stuff out to try and reverse-engineer some things, which would represent an extremely small percentage of those who try/succeed. In the end, if it's implemented properly it could do of great help. ~How much depends on acceptance (sales). Yes, parents should do a better job of parenting their kids (duh). How long have we been saying that though? Forever. Ergo, something else needs to be available to help and stop spamming FAIL for every thing, wow. Parents have been doing "FAIL" for years and years and it's not getting any better. I think solutions like this are better than nothing, yet they still need to be well-thought and implemented correctly. I think things like this and increased (good) parenting are needed.
