I don't drive too much these days, but even when visiting Vancouver and driving around Richmond... zero fart tips.
Sometimes I feel like... for nostalgia... I need to get rid of my current turbo domestic and pickup a Honda and put the biggest, loudest, most obnoxious fart time, a window banner, a shopping cart spoiler, and one of those static-straps that hangs down to re-live the glory days of automotive enthusiasm right around the time of Fast and Furious!
Or, maybe, a whistle tip...
