I haven't mentioned freeway driving, there's enough room for everyone to get along. My point has been on roads where there are not extra lanes to pass, say one on each side of the median.

Obviously 45mph for your case is with-in the law, but hardly with-in reason with a 20mph speed difference. I'll let logic take over at that point, it's obvious on a freeway you'll find cars going over 65mph at which point the 45mph minimum becomes can become even more dangerous, depending on traffic. If traffic is tight at rush hour, but generally moving along at 65mph, I'll leave it to you to say if doing 45mph is a grand and safe idea when prevailing traffic is safely moving along 20mph faster.

If you're scootin' along at 3am in the far-right lane, 45mph becomes much more reasonable with next to no traffic to deal with. Though, I'd never do that low on a TX freeway.

You can argue semantics and situational examples all day. Fighting road rage with road rage and further exacerbating the situation is not safe driving, as per some posters' opinions.
