My mother and father both drove under the speed limit for as long as I remember. Once day, after I had just turned 21, my mom and I had to go to an appointment somewhere and were running late. She's driving, speed limit is 25 in our neighborhood. I notice she's going a little fast and I see she's going 30.
Then 50 and coming up to a 4-way stop ... which she blows through. I'm freaking out of course, because I've never seen her drive like this and figure she's going to get us both killed, and say something like "Mom! What are you doing?" and she replies "I figure it's about time for you to know how things really work. I only drive super slow and careful when you're in the car so I can set an example. While I don't drive like this all the time, I'll do it if it's really important." Within the next 10 minutes she did 60 in a 35 zone and 85 in a 55 zone.
We got to the appointment on time.
I then knew where I got my driving style from.
My father wasn't faking it ... he always drove slow.
