only 3 reactions I can remember...
1) Gas station filling up, guy says my tires look like they're deflated, although I'm just on low profiles (245/30/20 at the time)
2) Driving through the Cassiar Tunnel, and 2 cars pull up afterwards telling me my car sounds hotter then a Ferrari
3) Parked under a tree at friends house, bird had laxatives or something, 1/3 of my passenger side was shat on. Had to pick someone up from DT and 4 pretty hot girls yell to me "you have bird shit on your car"...followed by giggles, while I was trying to make a right turn on Thurlow and Robson
