My buddy got pulled over on the conjunction of I-75 and I-285 once with me in the passenger seat. He got pulled over for "weaving in and out of traffic recklessly" according to the officer. We got off with a warning and he said if we're in a hurry, just stick to a lane and don't go over 90mph.

So yeah, don't go over 90mph on I-75 or I-285.
