I rarely encounter "road rage" no matter what I'm driving....I don't necessarily consider fast or aggressive driving as road rage (certainly not when I'm driving like that, LOL and j/k sort of.)
I think sometimes it's a matter of perception...what annoys me most is the sort of half-conscious, witless driving that seems so common. People meandering onto the freeway on-ramp without using turn signals, those who putter along in the left or middle lane doing 60 mph, the person who keeps attempting to speed past on the right without noticing there's a slow semi in that lane so they have to hit the brakes and end up even further back.
I don't now (sob) but have had a few pretty sporty cars - Porsche 911, Saab Viggen, Mustang. What I noticed then: people, usually young men, would try to "challenge" me to race them or generally drive like Froot Loops. Now that my two vehicles are a beater truck and a bland minivan, not so much.
I also think it's an age thing....for me, anyhow. As I've gotten older, I find I let the little things bother me much less. Someone wants to cut in front of me, zoom up the left lane to cut in when there's construction and the lane is closing, tailgate unecessarily...used to make me froth with irritation but now I'm like meh, you're driving like an idiot and I'm not...have at it.
I'll just make room and let you irritate someone else.
