subway pet peeve

I have to express a pet peeve that I was on the receiving end of this morning on the subway. So when subway trains leave the station, most of the time they jerk forward a little bit. This happens pretty much across the board on ALL trains. My pet peeve is when people think they can just stand in a crowded train without holding on, and then when the train jerks forward (and if they have been on a train for more than ONE STOP EVER they should know this is going to happen!) go FLYING across the train and run into people. People, if you want to read your newspaper, or use your blackberry, find a seat. Or at least fold up the paper so you can hold on with one hand. I will forgive people who are getting on train for the very first time EVER if that happens, but come on, no one wants to get slammed into by someone who knows full well they need to hold on.
