I used to get pulled over all the time when I had my tuned cars. When I bought my Lancer it got tailed a few times but never bothered, now that i have my truck and no infractions for 5 years I don't get bothered, ever.
Also for the person saying consent for recording, as far as I know in Alberta one of the two parties need to know they are being recorded. Not both.
I think profiling happens however i am sure it stops people being total douche's. I for one am for it as long as I dont get bogus tickets for it. If I start getting bogus tickets for being profile pulled over then it would get tired quick.
