They drive like hell on I 81 I know. Running the full length you get passed by at least 100 of them all doing 90 MPH...

That's because, especially in Ontario, the provincial police (depending on the day) will allow you to speed 15 kms (9 miles)over the speed limit. So speed limit is 100 kmh, it's not worth them pulling you over for 115 kmh or under (again unless it's a blitz that day or something)
I believe state police are a little stricter on the interstates and Canadian's forget that when travelling on the I 81...
