My speedometer is trying to mess with my head. A few days ago, it started sticking at zero. After a few seconds, it'd realize "Hey, we're actually moving!" and start working properly. Now today, I was going about 65mph. Then it decided to drop down to zero. For a moment, my tachometer was all "wut?! WTF?!" but it caught on a lot quicker than the speedometer. Heh.
Shame I just had the car in for inspection the other day. Else I could have been all "Yo, check that out, yo."
