Pretty sure anyone who has ever been behind a car has sped at one point. Unless of course you're in Richmond, where you drive 30 and don't signal.
I-5 is a fast highway, I wasn't exactly zipping by everyone, if anything I still had someone on my tail.
Just because I-5 is a fast highway, it doesn't mean that you should go faster. You were basically going 125 km/hr and you say it isn't that fast? You've got to be kidding me. 60 mph is about 100km/hr which is 20km/hr faster than the max speed limit on Canadian highways. The fact that you did more than 20 km/hr over the posted speed limit should've cost you more than $175. If you were travelling 20 km/hr over the speed limit here, you would've got a speeding ticket north of $200.
