Could you please tell me what the meaning of "together we brace a hundred times for impact" is?
The full text is here: It’s three in the morning, and we are making our way from southern to northern Utah, when the weather changes from the dry chill of the desert to the freezing gales of an alpine winter. Ice claims the road. Snowflakes flick against the windshield like tiny insects, a few at first, then so many the road disappears. We push forward into the heart of the storm. The van skids and jerks. The wind is furious, the view out the window pure white. Richard pulls over. He says we can’t go any further. Dad takes the wheel, Richard moves to the passenger seat, and Mother lies next to me and Audrey on the mattress. Dad pulls onto the highway and accelerates, rapidly, as if to make a point, until he has doubled Richard’s speed. “Shouldn’t we drive slower?” Mother asks. Dad grins. “I’m not driving faster than our angels can fly.” The van is still accelerating. To fifty, then to sixty. Richard sits tensely, his hand clutching the armrest, his knuckles bleaching each time the tires slip. Mother lies on her side, her face next to mine, taking small sips of air each time the van fishtails, then holding her breath as Dad corrects and it snakes back into the lane. She is so rigid, I think she might shatter. My body tenses with hers; together we brace a hundred times for impact. Educated by Tara Westover
