Something easy to make the roads a little safer, and irritate others a little less.
Now you may be saying "well if people would just move over or slow down so I could merge I would get up to freeway speed and everything would be just fine" and if you are, please slap yourself in the face, hard - maybe even consider using some sort of wooden spoon to really get the message across (I'll leave that to your discretion). The traveling lanes of the freeway are not for accelerating they are for traveling, at freeway speed. The on ramp is for getting up to freeway speed. If you would use the road for the intended purpose everything would be fine. By not getting up to freeway speed you are creating a domino effect. It may not cause an accident every time; it does cause congestion and confusion EVERY TIME.
Notice I said 'freeway speed' not 75 mph, that is intentional. A skilled driver looks far down the road and is able to see the relative speed of traffic and adjust their acceleration accordingly. The key is that your speed match the traffic you are entering; don't expect traffic adjust to your incompetence.
