I'm an Asshole?

When I'm in the car with any of my roommates and they are driving I'm scared to death because they will drive 1 car space from the car in front of us and not slow down a head of time; they wait to break.

So my foot often goes through the floor and I'm asking them to back up.

They all tell me to calm down.

Now they're saying that I'm an asshole because they drive fine and I'm the problem because I "drive erratic and slam on my breaks"?

What?

Yeah! I'm upset because I don't want to get crushed And die!

I give myself 5 cars of space on freeways. Not 1. I slow down when the car IN FRONT of the car in front of me hits their breaks so that I have time to break if I need to and it signals the car behind me that they may need to break.

I don't want to get rear ended so I don't ever slam on my breaks, hence all the space..

Why am I the asshole for trying to be safe and why do none of their arguments against me make sense? 😢
