Going home from school at around 1pm. The freeway is pretty much clear of cars so I travel faster than usual. The thing is, when I'm travelling 100-110 ish, it feel like I'm going 75-85 mph (I admit. I love driving fast, but I make every effort not to be reckless whatsoever). Seriously, I scratch my head and start to wonder, is this speedometer playing visual tricks on me or what? Has there been any speedo problem or anything that needs to be recalibrated or do my driving habits need to be recalibrated.
