If no one is ahead of me, I get the car up to at least 60, preferably 70, while on the ramp so I can comfortably merge in at freeway speeds at the first opportunity. Not only do I not go all the way to the end of the acceleration lane, but if I do see an opening, I will cross over the channelizing lines (before the ramp becomes the acceleration lane) to get onto the freeway. This is especially true if, to CMRivdogs’s point, the guy I am following onto the freeway is still going 30 or 35 even when approaching the acceleration lane.
