So this is what the black box thinks of my driving. The only one that requires any skill whatsoever is smoothness. Usage - I get the car home before 10pm for a perfect 10. Speed - I make you all follow me at 24mph everywhere. Smoothness - I opted to nearly cause two accidents to keep my score up. Unfortunately at a green light, someone decided to slam the brakes on to let a car turn right across us. Hence I lost 1.2 points on smoothness.
