Imagine you're driving on an empty road in the middle of Kansas. You're coming up to a 4-way stop, and there's not a car in sight in any direction. The speed limit is 50 mph. THree questions:
1) How fast are you going?
2) What do you do at the stop sign?
3) How fast are you going after the stop sign?
I've asked this question a hundred times in a training class I used to teach. Answers range from
50/0/50
90/75/90
What kind of car am I driving?
It really doesn't have much to do with the vehicle.
The car passenger and their response - that had everything to do with their baggage about your vehicle. Let it go.
