oh damn, boeing 747s dont count huh?
130 in the bimmer on I-5 by grapevine, 140 on that back of a GSX-R on 99 nearish visalia. in the bimmer it was quiet until I rolled the windows down, the wind noise was LOUD!!!the GSX-R; I had a helmet on, but it loud too. I'll never do that again. I was 18 and therefore stupid.
I drive 55 sometimes just to see what it's like, it's very relaxing actually. I sorta like it.
