low achiever

There's an intersection by my job that seems a bit risky. Two or three cars may be in the median, waiting their turn. It's always a little shaky as to which car will go first, how fast it will accelerate, and whether they'll be going straight or turning. For the most part, drivers navigate that intersection safely on a regular basis. As for me, I think I'll avoid that risk. I know great achievements can only be had if you take calculated risks, but I don't want to achieve great things while driving.
