Correct highway on-ramp speed?

Stop and think about it for a minute and you will see the fault in your logic. If you speed up to 55-60 on the ramp before you can see the traffic flow, by the time you are there to merge you would not have time to adjust your speed if there was no place to merge in, leading to a crash. You go 35 until you can see the flow, them accelerate to match the flow only when you see an opening.
