People who do 30mph on an on ramp to a highway where the speed limit is 65mph. Why do you do this?

1. My local section of highway has an on-ramp that turns into a quarter-mile exit lane for the next exit. A lot of people get on the highway with the intention of taking the next exit, and simply stay in the lane, never getting up to highway speed because they're getting back off a quarter mile up the road. This is always infuriating because I NEVER take that exit, and am forced to sit behind them while they cruise at 45 mph up to their exit while I'm trying to merge left with cars flying by at 70 mph.

2. DC has speed cameras on the entrances and exits to 395- ramp speed limit is 35/interstate is 55 Needless to say, people get hit a lot by these cameras and it makes merging (often from left exits) a nightmare

3. I assume they have a birthday cake in the car and don’t want to muss the frosting.

4. I see you've followed my mother-in-law onto the freeway. She gets on the on-ramp, sees a car on the freeway, oh, a half mile back or so, and panics and hits the brakes. Seriously, I don't know how she hasn't caused a wreck or twelve by now.

5. My dad does this, and I asked him why he does it, straight up, "I want to get good gas mileage, and you don't get good mileage by accelerating hard." So, there is one old man's answers.
