@hacks4pancakes This tends to happen a lot during traffic. I would call it zombie traffic. The worst is when they drive side by side (which is very dangerous but also bad as you'll hold up any traffic trying to pass you).

If they are matching my speed it doesn't bother me - but when they are constantly varying in speed and weaving it drives me nuts! Like cruise control exists people! It's worth learning how to use and it saves you gas!

Space cushion was something I learned in driver's ed and didn't really care about until I was maybe 10 years into driving. It has saved me from slamming my brakes and making dangerous last minute maneuvers for the better half of my driving experience. It's when you drive consciously about the space you have between the cars all around you - in short an escape route.

I'm surprised your dad is more annoyed while maybe a woman would be afraid of someone trying to follow but I figure they usually do that because they feel like if they speed a cop is more likely to stop them but not both of you. Solidarity on the road!!
