I drive a 2001 Lexus RX 300, and my parents just recently became "concerned with my driving". They claim that there is a "black box" somewhere in the back or something (they claim that it's in all cars..or at least the make of mine) that can tell them exactly where I have been and how fast I have driven. On the contrary to what they may say, I am a good driver (never gotten a ticket, or in an accident) and i don't speed. I go 5 mph over the speed limit TOPS. This is because they have made it quite clear that if I ever get into an accident/speeding ticket, I will have to start paying for my own gas and insurance. So anyways, I have nothing to hide, but I'm really mad that my parents don't trust me and think that I'm speeding and/or sneaking around (because I'm definitely not...). I just want to know if they are telling the truth about this little thing, or if they are just trying to scare me to make sure I'm not doing things I'm not supposed to be doing. Please give me as much details as possible, of where this thing could be, or if its real, and if they are telling the truth.
