一直有人在爭200m外多看兩秒就會看到了
(先不說當兵過的都知道175m人型靶有多大,
機車頂多有個頭燈讓你知道他在哪,
但是對200m判斷距離完全沒用)
實際上發生的事情是:
開始看的時間T=0,距離750m
看了三秒T=3,距離600m,決定等前面貨車
貨車通過5秒,T=8,距離350m
這時可能還沒沒注意到這台機車
(被當成遠方反光之類的
再看兩秒,T=10 ,看到機車了覺得很遠250m,開始過
滑出兩三秒進入最內車道時,T=12,150m,開始改看前面和右邊
迴轉車速10kpm,全長5m車道4m要化兩三秒完全通過
這時當然主要注意右方來車,被撞T=15,0m
勉強能判斷距離的最後200m,
4秒中有至少3秒正常人是在注意另一側來車了
更別說實際上要100m左右才真的能判斷速度
所以說當過馬路的人或車意識到這東西可能撞上來時
意識等於看到加頭腦反應,至少半秒
他已經沒有任何選項可以淨空車道了
看到=撞到
