It's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the US, the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep -- a hundred thousand a year.
Odhaduje se, že 31 % řidičů usne za volantem aspoň jednou za život. Statistiky z USA mluví jasně: 100 tisíc nehod na dálnici je spojeno s únavou, ztrátou pozornosti a usnutím. 100 tisíc za rok.
