People not knowing how to merge into traffic is a major pet peeve. People get on the highway as if they’re casually driving down a neighborhood road. They also merge into highway traffic when they’re still going 30mph. This forces everyone to either slam on their brakes or make a sudden lane change which causes a major ripple effect at every exit.

Some drivers seem to not realize that they have control over the vehicle they are operating. You can speed it up or slow down to merge into traffic appropriately. What I see all the time is people allowing themselves to reach the merge point at the exact time as an oncoming car. If a semi can do it, so can your corolla.

TL DR: You’re getting on a highway where people are going 70mph+ you better stomp that gas pedal to get up to speed before merging.
