I went out for a walk around my parking lot at work, and spotted a sharp looking black Audi A4 with a Crapra in it. Next to it was a Subaru WRX with a V1 in it.
The Crapra was on, so I went back to my car, grabbed my handy JTW laser tester, went back to the car with the Crapra and tried to set it off with my tester, but was unable to. Either the Crapra is really crap when it comes to laser, or it has really good filtering (ignores the JTW tester), or something. The V1 in the next car over wasn't turned on, so I couldn't test on that.
I should try my Hot Wheels radar gun on the Crapra, but with my luck the car's owner would come out and ask me why I'm pointing a toy ray gun at his car!
