Washington has never had a points system and I don't think texas does either. And all this slow down stuff is aload of bull, if you know the limits of your car and your limits then the speed limit is just a suggestion. The only reason the speed limit is in place is because of all the other stupid laws.
Look at the speed limit for starters, it's in place so that old people and young people, inexperinnced and experienced, nervous wrecks and nerves of steel.. can all drive at the same level.
Next how much does it cost to get a license? I think it was like 30 bucks when I got it, now lets look at another country where they don't have speed limits, it's like 2k USD. So only the people who need/want to drive do drive.
Next drinking, in that same country where they don't speed limits on a well traveled road(unless it's commute time, or there has been a accident) people start drinking from a much younger age and learn their limits, being drunk in public is also looked down upon, there for they have less drinking and driving laws because people have more common sense of what to do and what not to do when they are intoxicated.
Now my next point, people in that same country(again) know how to freaking drive, period. It's a divided freeway where in the really fun parts it's two lanes each way.. the left lane is for passing only, I mean passing only! You get over, pass, and get back over... not like the idiots do over here and just cruise in the passing lane. This country needs a autoban where you have to have an endorsment that you pay for and goto class for and are tested on.
