high vs drunk

Wham! Its going, going, going and caught :(
This guy was a little high according to him, according to his friends he didn't know where his legs were. borrowing a line from Robbin Williams he says "if only i can find my legs, i can drive". So he gets into his car, with his friends, who for the record were equally high and decides to drive within the speed limits so the cops don't stop them. After driving for about 15 minutes this guy hits the first red and stops. Waiting, waiting, waiting for it to turn green, 1 minute passes, 2 minutes ... 5 minutes, so he turns back and goes isn't there something wrong with this light?
"yeah, looks like its broken", comes the reply.
blue, red lights from the back, a cop.
"what seems to be the problem officer?"
"your licence and reg. please, you've been standing at this light for how long?"
"almost 15 minutes now, looks like there's something wrong"
"yeah there does seem to be something wrong, but it ain't the light. you guys have been here for the last hour and a half!!!"

at first it seemed like a briliant plan but now on retrospect it wasn't such a good idea, so my question is this...
when u drink and drive u tend to drive like crazy, when u'r high u drive 15 in a 45 zone???? go figure.
