Perhaps a better term would have been "takes a long distance to stop all that weight especially at high speeds" but I was trying to keep it brief.
My father was hit by a train. He was in his brand new (at the time) 1947 Chevrolet. The car stalled while crossing the tracks and would not restart quick enough. I guess he didn't have time to run from the car. Perhaps there was no cross arms or other warnings, maybe he was trying to beat the train. This time I wasn't there. He was not injured but the train slid him sideways for about a mile before it could stop.
