Ive personally noticed I take it way easier in the car now that I have the bike than I used to, because I think I get the adrenaline rush/speed demon thing out of my system, so now I find myself just putting along at the speed limit when I'm in my car, and blasting around when on the bike.
I drive differently, yes. But I drive my explorer slow as all hell now. If i want to go fast, I'll take out my fz.
Also if i'm in my car, i'm way more relentless. If somebody comes to a cross street - i'll just barrel down the road thinking "i dare you to pull out, i dare you"
i used to pass slow motorists on the dotted yellows in my car, now i dont even bother. I will try to wave or keep up with other bikers though.
