Aim for the back of the legs, arms, etc...
I don't plan on using it at a stoplight or whatever, again, it's used mainly for the parking lot at the ice rinks I go to. Past month, while doing adult league in phoenix, I've been told I wouldn't make it out to my car alive. Luckily I did. When I was in Flagstaff, and had every single fan wanting to lynch me... or in Tucson, after the referee gassed the goalie in the last 2 minutes of a 2-2 game, which resulted in Phoenix scoring and winning the game...
But yeah, I've moved it to the backseat for now.
